I'd say forget the AI buzzword hype and go back to programming something useful based on real transaction-level data like below (that can help you with any deal you find, from whatever source you have).Sales Comps & ARV estimate:Market Stats:AI won't be able to provide you anything close to this, nor does the RedFin/Zillow market data drill down into the market as deep as I do here.Additionally, if you understand how the leading LLM's work based on a black-box floating point matrix, you just can't trust their conclusions like you can with your own program.

If you only plan on owning 2-4 properties, then there's really no harm in self-funding them unless you know a better, safer way to make more than the going interest rate on that money (most investment mortgages right now are about 7%, maybe effectively 5.5-6% after taxes depending on your brackets and tax structure).
