The questions your work already asks
Title & settlement
“What’s open on this file that could hold up closing?”
Open permits, code cases, and tax delinquency on the property, the day the file opens.
Instead of: finding out the week before closing
Trades & suppliers
“Where is work being permitted in my trade this week, and how big is it?”
Issued permits by kind of work, value, and contractor, the week they are issued.
Instead of: Permit lists bought weeks after the fact
Service businesses
“Who just bought a house or finished a pool near me?”
New owners and finished work, at the start of a relationship where the property is the customer.
Instead of: New-homeowner lists and door tags
Agents & brokers
“What sold on my streets this month, and who is fixing up to sell?”
Every sale with its deed price, permits on long-held homes, and the full record on any address a client names.
Instead of: Mailers and word of mouth
Investors & wholesalers
“Which owners are behind on taxes with a code case open?”
Delinquency, violations, and sales joined property by property, and which way each one is moving.
Instead of: Monthly snapshot lists and driving for dollars
Lenders & risk
“Has anything happened to the properties behind my loans?”
Delinquency, condemnation, stop-work orders, and roof and renovation permits, followed property by property.
Instead of: Hearing it from the borrower
Government & institutions
“Where is blight concentrating relative to housing, this year against last?”
Vacancy, violations, and delinquency per thousand homes, on one definition from city to city.
Instead of: Records requests and months of cleaning
