Start with the payment you want to live with
A mortgage approval estimates what fits program guidelines. A personal housing budget answers a different question: what payment supports the rest of your financial life? Begin with a comfortable range for principal, interest, property taxes, homeowners insurance, mortgage insurance and HOA dues.
Arizona carrying costs can vary by community and property type. Condos and planned communities may have association dues, while insurance and solar obligations can materially change the monthly total.
Separate cash-to-close from reserves
Cash-to-close can include down payment, closing costs, prepaid taxes, insurance and initial escrow funding. Reserves are the funds remaining after closing. Using every available dollar for down payment may reduce the loan balance but leave too little flexibility for moving, repairs or an income interruption.
- Down payment
- Lender and third-party closing costs
- Prepaid interest, taxes and insurance
- Earnest money already deposited
- Funds remaining after closing
Put every option on the same worksheet
A lower rate obtained by paying points may take years to recover. A smaller down payment may preserve liquidity but increase payment or mortgage insurance. Seller concessions may reduce upfront cost while affecting offer strategy. Put each option into the same side-by-side model.
Pressure-test the budget before the offer
Consider how the payment feels if insurance rises, HOA dues change or a major repair occurs. Then connect the comfortable budget to a preapproval and property-search range. That creates an offer strategy built around the household—not simply the largest possible loan.
Use one worksheet for every property
For each home, record purchase price, down payment, estimated principal and interest, taxes, insurance, mortgage insurance, HOA dues, solar obligations and cash to close. Then show the funds remaining after closing. Using the same worksheet prevents a lower list price from hiding a higher monthly or upfront cost.
- Estimated total monthly payment
- Loan Estimate cash to close
- Required and voluntary reserves
- Known HOA or solar obligations
- A repair and moving-cost buffer
