Current residence allowing me to live rent free.

The 1031 exchange is what allows them to do this without having to pay tax on the gain or depreciation recapture. 

That means that unless your state allows you to just keep their money you have to try to re-rent the house.

Also, in order to get financing the lender wouldn’t allow SCI to dramatically overpay or they wouldn’t meet the debt service requirements.

@Ellis Moyewe really don't know a lot about this situation since there aren't many details in your post... but i don't think this makes any sense for anyone involved here...if it's a flip that's not selling, refinancing may not solve your problem and allow you to pay back the HML in fulland typically a sub to buyer wants a low interest rate... and if you refinance now you won't be getting a low interest rate, you'll just be getting whatever the market offers.and finally.... the vast majority of loans are NOT assumable. 

Additionally, I’m a licensed realtor in Pennsylvania, which has allowed me to expand my expertise and build a solid foundation in both investment strategies and the local market.I’m eager to connect with fellow investors, share insights, and learn from this amazing community.

i feel like the local FB groups will not allow me to advertise my STR there because they would label it as "soliciting".. any way to get around this so that it doesn't look like i'm soliciting?
