We are now building our portfolio through flipping, BRRRR's, and additional STR's until we reach our end goal of unique stays in the form of luxury treehouse STR's on secluded riverside locales. 

I used to live in that house before I moved back to California.

Can you get started with a house hack close by to where you live or move if you have to? 

Which part of the burbs do you live in? 

@Yu Xiao, using that property as a short term rental during the time you own it will open up some additional tax saving potential as will doing a cost segregation study to take advantage of some accelerated depreciation.  

The problem is that the tenants came with the investment property and while I have a lease with their names signed, I do have any additional info like their SS# or Driver's licence#.  

I'm particularly passionate about adding value to people's lives.

I currently reside in Turkey, but approximately 28 years ago, I was living in Long Island, NY.

Or maybe it could be a secondary unit in addition to the primary washer/dryer for larger homes that could use a third solution as a backup on a second or third floor.  

One way around the 20% down is to buy a house you will live in and rent out the other part (think duplex, triplex, etc).
