The main reason I am still considering it is because of my extremely low interest rate.

Small, SFH that you can somehow afford, pick an area with good fundamentals-safe, close to the main population centers.

(mid-term) Change to another SFR in the Bay area in 2-5 years (mainly for family purposes).2.

Then my main objective is to pay back my investor or investors asap.

Something else to consider would be that you already likely have cleaners, handyman services and the like in Orlando area.

My friend @Edgar Barbosa was also in the service and I believe he has used a VA loan. 

Servicing existing residents and leases upon purchase.

appreciate you taking time to reply, that's very considerateI was going to put the property in the LLC anyway for the normal reasons - I don't think there's any harm in that for now, I'll keep consulting for the main point for what parts might look like a "sale" of the property.

All three houses cashflow and she is not interested in selling at all as this is her retirement plan and main source of income, however due to excess cc debt, a high DTI, low credit score and lack of financing options, she is extremely cash poor. she is at the point where she could and I think should declare bankruptcy on those cc's, and move the houses out of her name. in order to get financing, all houses need to be in LLCs, which they aren't.in order to kill a couple birds with one stone, my mind goes straight to 1.

The main caveat with that is you may be limited on how much rental income you can use from your departing primary residence (the house you are buying now) when you go to buy the next one, unless it is at least 100 miles away.
