There is currently no plumbing, or HVAC systems in place.

Hello Memphis BP, I just wanted to share that I finally completed my first BRRR deal sorta.Purchase Price: 76k (I bought this property from a rehabber in 2019)Purchase Method: CashMonthly Rent: $1,150Appraisal: 190kCash out Refi 120k (minus 7k for closing cost plus points) cash in hand was roughly 113What I learned during the process: Important to show income on your taxes I have a W2 so not having my properties on my personal w2 did not kill me but if you're a full time investor trying to not pay taxes or showing properties as a lost may hurt you when trying to refi. 

Whats a couple good methods to determine local storage unit vacancy rates to analyze the need for more units in a market?

Rough plumbing in, drywall and tape over or backer board walls and porcelain tile if you are keeping this long term.

Down the road you’ll get an inspection but to make sure you don’t waste your time and money - verify the age and condition of the big ticket items - roof, HVAC, plumbing, wiring - those capex items.

However Deferred Sales Trust are one method of doing this.

I wish to try out this method, instead of just being a landlord.

You can search BP posts for people using the 'House Hacking' strategy, or the 'BRRR' method where people share their stories of similar ways to build capital creatively.   

If so, what are the benefits to the buyer of this method? 

Not giving you standing in court is a method of forcing folks to follow the rules.
