MHMFA will normally require that monthly housing (expense (mortgage payments plus escrow payments) not exceed approximately 25% of Borrower's "stable monthly income" (as defined in 761 CMR 21.43). If Borrower is purchasing a condominium or PUD unit, the monthly condominium or Planned Unit Development fee (homeowners association dues) for common elements/charges must be included in the monthly housing expense when calculating the above ratio.
