Episode notes
AI First Pass Caught Listing Errors
- Chad Coach Carson asked ChatGPT to analyze a 4-unit in Clemson after pasting the Zillow listing and rent estimates.
- ChatGPT found the sale price $345,000 and corrected Zillow's $1,150 rent to the actual $2,770 total, breaking rents per unit.
Cap Rate Looks Good Until Assumptions Change
- ChatGPT computed NOI, gross yield and cap rate showing ~6% unleveraged yield at $345,000 and ~5% at $400,000.
- The cap rate placed this student-market fourplex in a respectable market band but depended on the underlying assumptions.
AI Identified Rent Upside
- ChatGPT spotted rent-upside potential because current rents were low relative to market for Clemson student units.
- Chad noted comparable nearby units could reach $900–$950 per two-bedroom versus current $670–$700 rents.
