Since I'm a new immigrant with no credit score, a DSCR with 30-35% down payment is my only option, so the 50K need to include that down payment alongside all other costs (closing, rehab, etc). 

How many mortgage lenders have you spoken with to get qualified and discuss allowable down payment options?

Many good rental options in San Antonio/New Braunfels area.

There are a few options(1)You can get connected with the larger wholesaler firms in the area (2) go through PCPAO site and skiptrace the buyers of similar properties as yours, (3) hunt down the agents involved in the sale of properties similar to yours or go to local REI meetings and pitch it to the investors there. 

The condo will limit the rental options to age restrictions. 

In which case your reply would have been appropriate.He actually asked more specifically:"Is it possible for her to have that many hours (750h) by managing our 9 properties?"

In other words, asking for that can actually hurt you in negotiations. 

I property manage STR in the cape cod so this is actually good info

Please help I’m just trying to get to the truth, nobody has come out and said that it actually helped them make any money, it’s all just been hearsay and empty profiles.

If you find you are unable to raise the money for an all-cash purchase, switching gears to Fannie will only work if you have a LONG time to close in your PSA or have many extension options (which usually require more hard earnest money.)
