If you're looking to avoid a rather large tax hit, a 1031 is probably your best bet.  

I am a new investor in the Tampa Bay area and I am looking at single family mobile homes as rentals.

So a nicely decked out  cabin I bet would rent real well for STR purposes  Not sure about permits etc..

At one time I was looking at mobile homes in certain areas.

Trying to go to companies directly is rarely going to be your best bet. 

It looks like networking and meeting people will be my best bet.  

I'm betting your numbers look like mine, and CapEx saving is eating up a lot of it.

The two earliest popular and successful “gurus” were Jimmy Napier, whose speciality was investing in notes, mobile homes, and real estate “exchanging”, and John Beck, whose speciality was tax auctions, and complex series of exchanges in which John used near worthless lots acquired for pennies at tax auctions at full tax assessed value for exchange purposes, usually as a downpayment, or as collateral for a private note.

Doing this like a brrrr I see as the best bet, for example my property does still have room for improvement adding a bedroom and bath to the primary structure and then the ADU.

I'm sure your cost of living is less given you're in the RV, can be mobile (see the country, work remotely) etc.
