What These Terms Mean

Principal & interest: Monthly repayment of borrowed principal plus interest. Does not include taxes, insurance, HOA, or mortgage insurance.

PMI / MIP: Mortgage insurance applies with lower down payments. Conventional PMI estimated at 0.50% annual when down is under 20%; FHA MIP follows HUD’s current schedule based on term, loan size, and LTV.

Homestead exemption: Texas school-district exemption of $140,000 reduces the school-tax portion of property taxes for qualifying primary residences. This estimate models school taxes as ~40% of the total tax bill.

Tax assessment ratio: Harris County typically appraises resale homes near 80% of the recent sale price due to appraisal-cycle lag. New construction is usually appraised at the contract price (100%).

Cash to close: The cash you bring to the closing table: down payment + closing costs + (if applicable) upfront FHA MIP if not financed into the loan.

Closing costs: Planning estimate for lender fees, title/escrow items, prepaid taxes and insurance, appraisal, and other buyer costs. Actual closing costs come from the lender and title company.

FHA upfront MIP: FHA’s 1.75% upfront mortgage insurance premium can be financed into the loan (most common) or paid at closing as cash.

Loan term: How long the mortgage is scheduled to be repaid. A shorter term usually means a higher monthly payment and less total interest paid.
