Would a bank even allow us to mortgage multiple buildings on a single lot without it being subdivided?

., "I will buy at least one single-family home, duplex, triplex, or fourplex before the end of 2019") and then do it.

Quote from @John Clark: Did you check for houses on the auction list,  or you can check with banks and look for REOs and convert that into a single family home and house hack or turn it into a Airbnb. 

I am considering purchasing empty lots priced roughly $10-15K below market value.My plan is to offer owner financing for the land.These lots have water, drainage, and electric connections available, and mobile homes are permitted.The area is experiencing significant development, with the lots surrounded by new single-family homes.I would really appreciate any advice, feedback, or suggestions.Thank you

Not one single strategy will work for every property. 

The newest outdoor is still advertising 1st month free as they haven't filled up, and I spoke with the climate controlled owner/builder yesterday (he's a pretty big REI in the area), and he made it sound like he hadn't leased a single climate controlled unit since they opened a few weeks ago.I recently purchased a 140x45 warehouse with low ceilings and had debated doing self storage, but my market seems very saturated.

I am going to be lending to an investor on a single family home. 

If its a single family home its a far simpler analysis.
