I now live out of state, but I still have a 4 acre property near the crossroads (on 111 & near 77) in Lavaca County, TX that I need to do something with.

People are looking to live smaller or some are being forced to live smaller, hence the insane growth in apartments and storages.

And or they simply dont understand their target renter market as they have never lived in those type of neighborhoods and just have no experience with the life long renter.

You start by mentioning your age... you'd need everything to go just right for the rest of your life to make, best case, $400 or less additional each month net cash flow. 

Just to confirm my understanding, you are living in a side by side duplex in Miami - you want to renovate the other side that you aren't living with a renovation loan?

A duplex where I live and the duplex that was offered to me.

The 'investor' promises that the homeowner can continue to live in the home and repurchase it later or promises them new financing.

I really trusted my agent and knew several people who had invested in Reno so I took the leap after trying and failing for years to buy my own home in really high cost cities where I lived (NYC, DC, SF Bay area). 

Also, if it fits your budget and your business needs a write off BPCON lives up to the hype. 

What about while I live there I wanted to rent out the other unit or units, is this allowed under USDA?
