Pencil is a free rental property analyzer for Dallas–Fort Worth investors from 5th & Brick. Enter an address. Pencil pulls public records plus value and rent estimates, then compares DSCR and conventional loans side by side. For each loan you see the estimated payment, monthly cash flow, cash-on-cash return, DSCR and cash to close. Prices show as a range, not one number, so you keep room to negotiate.
