The plaintiff, Evelyn P. Lonergan, is the owner of a building, located at 1166 Main Street in Willimantic, consisting of two separate units rented as retail stores. In April, 1962, her husband began negotiating with the defendant’s district representative for the leasing of the store that was vacant. Her husband, now deceased, informed her of the negotiations, and she authorized him to enter into a lease on her behalf for a reasonable period of time of approximately five years.
The written lease was prepared by the defendant. The lease, which has been made a part of the record, was for a term of five years beginning May 1, 1962. Paragraph 14 of the lease, however, contained the following provision for renewal: “Upon the expiration of the term of this Lease, the same, including this clause, shall automatically be extended for a period of one year and thence from year to year, unless the Lessee shall give notice to the Lessor of termination at least sixty (60) days before the end of the original term or any extension thereof.”
The plaintiff, claiming that the lease did not create a right to perpetual renewal in the lessee, on numerous occasions demanded that the defendant vacate the premises upon the termination of the five-year term on April 30, 1967. Nonetheless, the defendant occupied the premises from the date of the lease and indicated no willingness to vacate voluntarily.
*124 The action in four counts was instituted by the plaintiff on December 3,1969, claiming possession of the premises, damages and cancellation of the lease. The case was referred to Hon. Joseph E. Klau, state referee, who, upon a hearing, found the issues for the plaintiff on all counts and granted all of the relief sought, including $9485 in damages. The defendant has appealed from the judgment.
I
The defendant has assigned error in the conclusion of the referee, hereinafter referred to as the court, that the language of the lease could not be interpreted as creating a right in the lessee to renew the lease perpetually. The court’s conclusions are to be tested by the finding.
Brockett
v.
Jensen,
Although this is the first occasion this court has had to rule on the issue, it is well settled in most other jurisdictions that, absent statutory provision to the contrary, the right to perpetual renewal of a lease is not forbidden by the law, either upon the ground that it creates a perpetuity or a restraint on alienation or upon any other ground, and such provisions, when properly entered into, will be enforced.
Nakdimen
v.
Atkinson Improvement Co.,
Courts do not favor perpetual leases, however; thus a provision in a lease will not be construed as conferring a right to a perpetual renewal “unless the language is so plain as to admit of no doubt of the purpose to provide for perpetual renewal.”
Thaw
v.
Gaffney,
In this connection, we have stated that in determining the intention of the parties to a lease, “[t]he controlling factor is the intent expressed in the lease, not the intent which the parties may have had or which the court believes they ought to have had.”
Ingalls
v.
Roger Smith Hotels Corporation,
The language in paragraph 14 of the instant lease, insofar as it purports to create in the lessee the right of perpetual renewal, is far from clear. It states that, upon the expiration of the original five-year term, the lease, “including this clause,
shall automatically be extended
for a period of one year and
thence from year to year, unless the Lessee shall give notice
to the Lessor of termination at least sixty (60) days before the end of the original term or any extension thereof.” (Emphasis added.) Nowhere in the provision appear any of the words customarily used to create a perpetual lease, such as “forever,” “for all time,” and “in perpetuity,” words whose presence or absence in a lease is of considerable significance to a court in deciding whether a right of perpetual renewal was intended by the parties.

Kilbourne
v.
Forester,
Moreover, neither paragraph 14, nor any other clause in the lease, provides for escalation of rent beyond the $175 per month agreed upon by the parties in paragraph 3. Of course, failure to include an escalation clause is not fatal; perpetual renewal upon the same terms as the original lease is an enforceable option.
Vokins
v.
McGaughey,
A review of the lease in its entirety establishes that there are sufficient facts to support the court’s conclusion that the instrument does not create a right in the lessee to renew the lease perpetually. However, while the language of paragraph 14 did not clearly and unambiguously express an intention to create a perpetual lease, it specifically provides that the lease should be extended upon the expiration of the five-year term “for a period of one year and thence from year to year.” In some cases, where the clause in question provides for renewal or extension only “from year to year,” courts have concluded that the lessee does not thereby have a right to even one renewal but rather that what results is a tenancy from year to year terminable by either party upon proper notice.
McLean
v.
United States,
supra;
Tischner
v.
Rutledge,
We conclude that the language in paragraph 14 confers upon the lessee the right to one renewal for a period of one year beyond the term of the original lease, and establishes thereafter the possibility of a periodic tenancy terminable by either party. Thus, although there is ample evidence to support the court’s conclusion that the language of paragraph 14 does not create a right to renew the lease perpetually, it does not follow therefrom, as the court also concluded, that upon the expiration of the original term the lessee became a “tenant at sufferance,” i.e., one who came into possession of land rightfully but continues in possession wrongfully after his right thereto has terminated.
Welk
v.
Bidwell,
*130
The court’s error in this respect, however, is of no significance in this case. Under the terms of the lease, the defendant’s right to possession of the premises, as we have indicated, terminated on April 30, 1968, with the expiration of the one-year renewal period. At trial the plaintiff acknowledged the defendant’s right to possession during this one-year renewal period and declined to make any claim for damages suffered during that period. The plaintiff, however, has consistently manifested an intention not to treat the defendant as entitled to posssession for any length of time beyond the expiration of the initial renewal period; although the defendant continued to offer rental payments, the court found that on numerous occasions after the expiration of' the lease the plaintiff demanded that the defendant vacate the leased premises, and it found that the plaintiff never intended the lease to be renewed perpetually by the defendant. Accordingly, after April 30, 1968, the defendant, in refusing to vacate upon the plaintiff’s demand, continued in possession wrongfully and became a tenant at sufferance.

See
Welk
v. Bidwell, supra, 609. The court correctly concluded that the plaintiff was entitled to damages for unlawful retention of the property by the defendant after May 1, 1968, these damages consisting of the fair rental value of the' property for the period during which the defendant
*131
remained in unlawful possession. Implicit in this conclusion is the further conclusion that the plaintiff on May 1, 1968, also became entitled to immediate possession of the premises. See
Welk
v.
Bidwell,
supra, 608-609. The court, indeed, adopted this conclusion in its judgment, wherein it stated that “the plaintiff is entitled to immediate possession of the premises and for damages for unlawful . . . [retention]
since May 1, 1968.”
(Emphasis added.) This court will not remand a case to correct an erroneous conclusion where the judgment is properly supported by valid grounds.
West Hartford
v.
Willetts,
II
The defendant next assigns error in the court’s evaluation of the damages due the plaintiff as an amount totaling $9485. This sum represented the difference between what the court concluded to be the fair market rental of the property and the amount actually received by the plaintiff, the period of computation extending from May 1,1968 — a year after the original five-year term of the lease expired — through June 15, 1973, the date on which judgment was rendered.
The obligation of the defendant, as a tenant at sufferance, with respect to damages was to pay the reasonable rental value of the property which it occupied without the plaintiff’s consent.
Welk
v.
Bidwell,
Ill
The defendant also assigns error in the court’s conclusion that the lease was signed as a result of a mistake on the part of the plaintiff and her husband and that this fact, in combination with the inequitable conduct of the defendant’s representative, entitled the plaintiff to, inter alia, cancellation of the lease. A prerequisite to the court’s exercise of its power to grant the equitable relief of cancellation of a written instrument is that the relief otherwise available be wholly inadequate to do justice.
Benassi
v.
Harris,
Moreover, the judgment of cancellation based upon this conclusion conceivably would entitle the plaintiff to a different kind of monetary relief from that actually provided in the other portion of the court’s judgment awarding damages. See, e.g.,
Robert
v.
Finberg,
IV
Finally, error is assigned in the court’s conclusion that the plaintiff’s husband had no authority to hind her to a lease exceeding five years, so that to the extent that the instrument purports to hind her to a lease exceeding five years it is of no force
*134
and effect. In light of our discussion of the legal effect on its terms of paragraph 14 of the lease, however, it is immaterial whether this conclusion was erroneous, since the plaintiff’s rights to immediate possession of the subject premises and to recovery of damages from the defendant as of May 1, 1968, the only forms of substantive relief properly granted, would remain unaltered. Thus we need not review this conclusion since to do so would not affect the final result.
Sea Beach Assn., Inc.
v.
Water Resources Commission,
There is error in part, the judgment is set aside and the case is remanded with direction to render judgment as on file except as corrected to accord with Part III of this opinion.
In this opinion the other judges concurred.
Notes
The presumption that a periodic tenancy has resulted can be overcome by a finding of a contrary intention on the part of the lessor alone.
