Frequently asked
About this calculator.
What's the difference between this and a basic affordability calculator?
Most "affordability" calculators give you one number: max purchase price. This one runs three tests in parallel because the right answer depends on which constraint binds for you. Your lender cares about DTI, your wallet cares about take-home cash flow, and your future self cares about cushion for surprises. The right purchase price is the one that passes all three.
How are property taxes auto-calculated?
We use 1.8% of (purchase price × 80%) annually as a national-average illustration. Real property tax depends on your county, homestead exemption status, and millage rates — Florida runs ~1.0–1.5%, Texas closer to 2.5%, California Prop-13-restricted around 1.2%. We'll quote your actual property tax once we have the address.
How is home insurance auto-calculated?
Single-family and multi-family: 1% of home value annually. Townhome: 0.5% (smaller exterior to insure). Condo: flat $150/mo (master policy covers most of the structure). South Florida runs significantly higher than national average due to wind/hurricane exposure — actual quotes can be 2–3× the auto-calc. Get a real quote before relying on a number.
What is "cash flow" status here?
Take-home pay minus housing PITI minus lifestyle expenses (fixed + variable + existing debt + savings). Comfortable: $1,000+ left over. Tight: $500–$1,000. Strain risk: under $500. The cushion matters — it's what absorbs car repairs, medical bills, lost income, and the everyday surprises that destroy households who bought at the absolute top of what underwriting allows.
What loan types do the DTI thresholds reflect?
Conventional 28/43 (front/back). FHA 31/43. VA n/a/41 (no front-end cap, residual-income test instead). USDA 29/41. Jumbo 28/36 (strictest). These are agency-standard caps; True Blue has access to lenders that go higher with compensating factors.
