With $50K and a DSCR loan, your budget will likely cap at properties in the $150K-$170K range, depending on the closing costs and any repairs needed.

And what is your price range and are you looking for turn-key properties or something along the lines of a "fixer upper"?

@Arsen Atanasovski first of all, you can’t buy even a mobile home in my market for $50k but yes I do help people in all price ranges here. 

Cursory research tells me places like Southland or Frisco have a good upside but we can be persuaded in all price ranges.

If you buy a hot water heater for the other unit, you can write off 100% because you have no personal use of that hot water heater. etc.

Good question, they seem to be all over the place depending on the area and I am not an insurance specialist, I think typically 1.5-2x normal rates but I could be off by a bit i have been honing in on White Hawk if you know that development and its in the pines but it does have water system with hydrants but volunteer fire department ..

Don't forget to change all your faucet aerators and shower heads to low flow it makes a huge difference as well as far as water usage and saving HOT water.

I would say get to no many neighborhoods.Also not much in 200K range any more.$300K is the new $200K. 

Why not start with a small turnkey rental property and test the water?
