Features
Source, underwrite, and close in one place.
Five tools carry a deal from a raw address to a closed transaction. Everything else supports them.
Deal Analyzer
Find the most profitable exit before you make an offer.
Enter an address and Basis runs Buy & Hold, Fix & Flip, BRRRR, and Wholesale in parallel, with real financing math behind every number: LTV and DSCR modeling, hard-money terms, refinance economics. Skip the spreadsheet and see which strategy wins first.
Scoring
Deal score, confidence score, and risk score, never collapsed into one number.
Every deal gets three separate 0-100 scores instead of a single opaque rating. Deal score measures financial attractiveness. Confidence score reflects how much to trust the underlying data. Risk score flags deed issues, tax delinquency, and distress signals. All color-coded, so you can scan a queue in seconds.
AI Analyst · powered by Claude
Every deal gets a second opinion from Claude.
Basis sends the full underwriting snapshot to Claude, Anthropic's AI, for every deal you analyze. It runs alongside the deterministic math, never replacing it, and returns a headline take, a ZIP grade, a per-field sanity check on your inputs, and a risk list grounded in real Census and HUD data.
AI opinion - verify locally before money moves.
Workable BRRRR, but the rent assumption is carrying the deal.
All-in at $90K against a $115K ARV leaves a real equity cushion, and a 75% refi returns most of your capital. The margin depends on hitting $1,395 rent, which sits above both local comps and HUD fair market rent.
- · Median household income $52,400; rental vacancy 6.1% (Census ACS)
- · HUD fair market rent for a 3BR here is $1,312/mo
- · All-in $90,000 vs $115,000 ARV leaves a 22% equity cushion
Your numbers vs the market
$115,000 sits inside the $112,000-$118,000 comp range for the ZIP.
$1,395/mo is 6% above HUD FMR of $1,312 and above recent local comps.
$28,000 is typical for a cosmetic plus systems refresh at this age.
Modeled at 2.0% of ARV ($2,300). Lucas County runs closer to 2.3%.
Risks the formulas can't see
- Rent is the binding assumption. Letting at HUD FMR instead of your estimate takes DSCR from 1.30 to 1.19.
- Taxes are modeled below the county effective rate. Verify the bill with the Lucas County Auditor before closing.
- Applying both suggested changes together takes DSCR to 1.14, thin for a 75% refi.
Suggested input changes
Rent $1,395/mo $1,310/mo
Aligns with HUD FMR rather than the top of the comp range.
Taxes 2.0% 2.3% of ARV
Matches the Lucas County effective rate. Adds ~$345/yr.
