OpenHouseMath is the mortgage calculator of Iron Harbor Mortgage, LLC, for homes in Texas and Colorado. Ask what a home would cost and it prices it from the lenders' current rate sheets: every rate on offer, each with its APR, monthly payment, points or lender credit, and cash to close.
If you're not seeing all your choices, the choice is being made for you. So OpenHouseMath shows them: the lowest payment, the rate with about zero points and the least cash to close, and how long it takes for points to pay off. Compare down payments, terms, credit scores and loan programs, FHA and VA included where offered, or a whole range of prices.
Selling? The net sheet shows what you'd walk away with at each list price, after commissions, title costs and your payoff.
Ask to try the options yourself and an interactive card opens in the chat.
Markets: Austin, Houston, Dallas / Fort Worth, San Antonio, Galveston and Huntsville in Texas; Denver, Colorado Springs and Chaffee County in Colorado. No sign-in. NMLS #349828 · Equal Housing Lender.
OpenHouseMath is #9,591 of 11,065 Claude connectors by popularity, down 528 places in a week.
