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, 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.
