Parcel cardHow parcels open on phones
Underwriting
Underwriting defaultsLoan, taxes & opex prefills for every underwrite
These prefill every parcel's underwriter (units shown on each field). The profile is auto-picked per parcel (5+ units / mixed-use → commercial); per-parcel price & rent still reset on each tap.
Verified-equity basisHow a deed pull's open liens net against value
After a deed pull, Conservative floor nets value against each loan's recorded original principal (no paydown credit); Amortized estimate instead estimates the balance today on a 30-yr schedule at the origination-year rate (Freddie Mac).
CaveatsAn estimate, not a payoff quote: the real note rate and term aren't recorded, and interest-only / balloon / HELOC loans don't amortize this way (a HELOC's recorded amount is its credit-line max, not the drawn balance). Floor is the safer number; amortized is the more realistic one.
Default underwriting assumptionsYour starting rents per bedroom + owner-paid utilities
Your own starting numbers — they seed underwriting (the rent anchor + the buy-box money criteria read them); override per parcel.
How they're usedThe underwriter seeds from your default rents (trusted above RentCast, which reads as a post-rehab high-end), falling back to the HUD SAFMR floor for any bedroom you haven't set. Utilities default to St. Louis flat rates and apply to multifamily only (single-family = tenant-paid); set $0 if tenants pay.
Default rents by bedroom ($/mo)
Owner-paid utilities — multifamily ($/mo)
Cap rate (5+ unit value)Cap rate by block grade for the income-approach value
Sets the cap rate behind the income-approach value shown on 5+ unit (commercial multifamily) parcels — value = stabilized NOI ÷ this cap rate, floored by comparable sales. It's keyed on block grade (1 = healthiest … 5 = most distressed); St. Louis City workforce stock trades well above the institutional ~5.6%, so the defaults run 6.5–12.5%. Each field below explains itself.
Scoring & grading
Lead score weightsPoints per signal, opt-in extras & neighborhood bumps
Each signal adds points to a parcel's lead score when it's present (a negative value subtracts). Each field below says what triggers it.
Extra signals (off by default)
Toggle on to fold area context into the score; set a negative weight to penalize instead of reward.
Neighborhood bumps
Add or subtract points for every parcel in a chosen neighborhood (e.g. +2 to a target neighborhood).
Grading models
ARV value-confidenceComp thresholds for the A–F ARV grade & band
Tunes the A–F confidence grade + honest band on the recorded-sale ARV (card & Pipeline). Each field below explains itself.
Rent confidencePenalties & cutoffs for the A–F rent-anchor grade
Tunes the A–F rent-confidence grade + band on the Underwrite rent anchor. There's no market-rent comp feed for STL, so confidence tops out at "model + HUD SAFMR agree, bed/bath known" — never comped. Each field below explains itself.
Buy-boxPass / Maybe / Fail acquisition gates
Your acquisition criteria → a Pass / Maybe / Fail verdict on the Underwrite tab, on the numbers you enter — covering your fact gates (units, lot, neighborhoods, crime/block grade, flood) and money gates (DSCR, cash flow, cash-to-close, equity %, rehab) in one criteria ledger. Each field below explains itself.
Neighborhood classWeights for the A–F area-quality grade & choropleth
Grades every parcel's area A–F — a read distinct from the lead score (seller motivation): area quality, not the owner. It blends census-tract income, the crime & block distress grades, and tract vacancy, with a light amenity nudge, calibrated to the St. Louis distribution. Set how much each input counts below; it's display-only — out of the lead score. The map chip "Neighborhood class" paints the green→red choropleth. Each field explains itself.
Property classWeights for the A–F building-quality grade & choropleth
Grades every residential building A–F — the property half of "class", distinct from the area-quality Neighborhood class (vacant lots & commercial parcels aren't graded). An honest proxy: St. Louis has no condition feed, so every building starts at a neutral C and age never penalizes it (the City's stock is nearly all old). Public distress moves it down (board-up, vacant registry, demo, 311, stale inspection, value gap); positive evidence moves it up (new construction, recent rehab, abatement). Set how much each signal counts below; it's display-only — out of the lead score. The map chip "Property class" paints the green→red choropleth. Each field explains itself.
