Compare the monthly costs of two apartments using the same payment assumptions.

Compare monthly costs

The amount a bank is willing to lend may not fit the household budget you want to maintain. Use the same expense categories when comparing two homes rather than looking only at the advertised mortgage payment.

Prepare two budgets: one for a normal month and another with a specific change, such as higher insurance, a special assessment or an equipment repair. This shows where costs could increase more clearly than adding an arbitrary percentage to the total.

Use one budget without counting taxes twice

Cost	What to verify
Principal and interest	Loan amount, loan type and the payment in the lender’s written estimate.
Property taxes	Current bill, applicable benefits, and whether already included in escrow or maintenance.
Building charges	What common charges or maintenance include; exclude items counted elsewhere.
Insurance	Your own policy, additional coverage and deductibles; do not assume the building pays for everything.
Assessments	Amount, payment schedule, expected end date and whether another project is proposed.
Utilities and parking	Actual inclusions, separate meters, parking rights and recurring charges.
Repairs and replacements	A household reserve informed by the property’s condition, not a promised universal allowance.

The Loan Estimate distinguishes principal and interest from the projected total payment. Read that breakdown before adding taxes or insurance again. CFPB — Loan Estimate explainer

A fictional comparison that changes the decision

Suppose a condo has these illustrative monthly costs: principal and interest $3,600; taxes $650; common charges $550; insurance $90; utilities $180; assessment $150; and repair savings $200. The planning total is $5,420, not $3,600. These are invented amounts, not a current mortgage quote or a Queens market average.

If the assessment ends, the same assumptions produce $5,270. If taxes and insurance later increase by a combined $200, the original budget becomes $5,620. Compare those amounts with your income after tax and other commitments.

For a co-op, rebuild the table from its actual maintenance breakdown. Do not add the building’s property taxes again when they are already included. For an all-cash purchase, remove loan payments—not taxes, insurance, building fees or repairs.

What to settle before making an offer

Obtain current tax bills, building statements and special-assessment notices. Ask for an insurance quote for the address and have the inspector identify replacements that may be needed soon and should be budgeted for. Label each amount as confirmed, estimated or pending.

Is a lower common charge always better? Not by itself. Investigate what is included and how future work will be funded.

Can I count expected rent toward affordability? Keep a separate rental scenario until lawful occupancy, lease facts and the lender’s treatment are confirmed.

Bring two or three listings to B Square Realty for a side-by-side property discussion. Your lender, attorney and insurance professional should confirm the figures within their respective roles.
