, see that under "sale conditions" it's listed as 1031 Exchange, what affect would that have on me - somebody interested in purchasing their property?

I would consider the tenant's past, as well as the condition of the unit, my local market, and other factors.

Purchase price: $123,000 Cash invested: $50,000 Sale price: $210,000 House was empty for 2 years before we took over, is was in deplorable conditions but in a C/B- area.

I’ve been manually scouring Zillow/MLS for deals, but it’s time-consuming, and I’d love to streamline this.2.Has anyone experimented with using machine learning models (like classifiers or regression models) to rate properties based on their condition from MLS listing photos?

I've never had to use hard money before, so I am not sure what type of conditions are reasonable.

I'd likely just agree to break the lease with a couple months of rent as a penalty rather than force these people to continue being tenants in my property....you never know what will happen to the condition of the property.
