Depending on what you find available and how many possessions you have but it’s likely possible to find a decent sized duplex to purchase.

I also believe that your Lot area has to be a minimum size in order for it to be considered "by right"I remember that some of the reasons why I didn't convert duplex to triplex:1.

With more and more institutional investing jumping onboard, the halving, and now you can buy Bitcoin with Paypal or the Cash App or Robinhood is making it even easier for people to jump in with any size investment. 

New Mexico has an unfortunate law against prepayment penalties for DSCR Loans on 2-4 unit multi that requires higher rates, but they don't apply to 5+ and I've seen some people have success with that size range in NM

People paid alot for parcels that couldn't be developed without a variance for minimum lot sizes or otherwise worthless. 

Lower turnover means happier residents, but it can also translate into less operational stress for you.Max Occupancy: The size of the home and local regulations will determine how many residents you can house.

Setup your filter to show you properties similar to what your looking for in the area your looking for (size, # beds/baths, etc.).

Given the size of this place, remediation could easily run over $100K, which I am sure you would not want to be responsible for.

likely going to be a bit too small ($ size) for most DSCR Lenders that do Mixed Use unfortunately

Lol, I have a similar story but I got off easy....I had my guys digging footings for a remodel in a little SoCal beach town when we found bones - some good sized ones.
