You have many options for low down payment on a duplex (2-Unit) these days between FHA, Home Ready and Home Possible (if you or the area you are trying to buy in qualify).

Note: The house is under warranty, so the builder’s have shown low urgency to these matters, but none the less the repairs are done free.

Galvanized inside the house rarely actually leaks or breaks, by the way - the bigger problem is the pipe corrodes so bad internally that you get ridiculously low flow & water pressure from the line, and bits of corrosion break loose and clog internal water passages in appliances, get caught in valve seats, etc. 

Lot of vacant lots, park owned homes with relatively what id consider a low lot rent, low lot rents....

What makes you stand out in the crowd?

Low credit score will mean a higher interest rate, but the funding is definitely possible.

I have been analyzing rental properties in my area and the BiggerPockets calculator has been showing cash on cash return on investment between 2% and 4%, which I found to be quite low.

these are called low value assets and low balance loans.. its a widely known fact in the standard mortgage industry that these are the highest risk.it cost as much to foreclose on a 40k loan as a 400k loan.. there Is no money.. and those properties tend to be in less desirable areas or flat out war zones or worst area of a city..

I think that is low.  

I’ve sent out emails to agents with inquiries because I hoped that maybe there were properties that were not being listed, so it’s good to know that the odds are still low so I can tailor my search to another type of investment.
