So basically they would be putting in 20% of the purchase price of the actual building only.

I have a couple of connections that build larger ground up multi family in the Houston area. 

Airdna because it doesn't account for a pool says it will bring $136k (my 2/1 with no pool on same mountaian does $110k-$120k) but in reality even in this market the new build will do $275k-$300k as it has a few other cool features Airdna doesn't account for.

I bought the building that my C corp business rents with a LLC company I own.

Purchase price: $255,000 Cash invested: $91,202 4 Bedroom, 2 Bathroom with Garage (New Build) - Purchased this one with a partner (50/50) What made you interested in investing in this type of deal?

With the 2019 ADU law, we are considering converting the duplex to a single family home plus ADU, so that we can build a DADU in the ample backyard.

now you're building equity.

Additionally, I aim to build my network and finding other investors, property managers, agents, and wholesalers in middle Tennessee or other areas in which I might one day invest.

I'm not sure if you can build in the floodway. 

Slowly build up your cash reserve and equity.
