I will still use alt. lenders from time to time depending on the circumstances but I will also achieve similar LTC financing through traditional banks and when I go to my capital partners with a term sheet for 85% LTC through a traditional bank with a fully capitalized interest reserve, healthy contingency funds and soft costs built in and the real estate great, its far easier to raise capital because far less equity is required to fund the deal but this all starts with the quality of the real estate.

I was thinking of starting a rent increase for my 1 bedroom tenant voucher due it being low and well under fair market value(Based on  hud and zip code) but my tenant is in the process of having a caretaker for her disability and getting approved for a two bedroom voucher.

Buyers don't look for financing and its foreign so they don't jump on a forsale listing on zillow.I've had the best (only) luck with zillow rental adds,   starting with the pitch;  rent to own, live in a great home while you pay off owning it. 

5 units+ could be a good place to get started.

My two favorite loan options for getting started are the FHA 203k or the Fannie May Home Style. 

I have recently started writing down addresses of run down or abandoned properties that I would like to purchase, but I only have the owner's name.

I’d like to start off by house hacking a multi-family unit. 

You can start by not calling us Boomers, lol.

Less risky and you can have a better start.

Sounds like you've got a good start with one STR.
