Look at the GIS property tax files for lots near you of similar size and recent sales for a price.Trailers are worth nothing.  

I don't think you can go wrong if you have the liquidity and the market is strong. don't forget that hotels are built in the middle of nowhere brand new and do fine. if you want me to look more closely at it send me a DM, this is ours right here that we proposed so you can see the style but it's 81 residential units, 45000 sq ft, 6000 sq ft of retail, no parking. on your assumptions, your occupancy rate looks high. pull some hospitality reports in the market and see what it is. your exit cap looks about right for what I've seen in hospitality.

Most of the lots aren't advertised for sale, but you can use the GIS system and other resources to find and contact the owners.

I invest there from California and will be closing on doors #13 and #14 next month (duplex).The city is going through a major revitalization effort and lots of investment.

We’re likely closing in on 19 straight months where wage growth has topped new lease rent growth – which means rent-to-income ratios are retreating again (Parsons).”

You're going to need 20% down plus closing costs for just about any loan product out there, DSCR included.

@Angelica Walker sounds like you have a good contact above already but would certainly recommend connecting to some real estate groups close to you. 

Interesting and to me a bit dodgy-why not proper sales where they represent the seller and try to get them the most money they can?

With $40,000 in cash reserved for contingencies and closing costs, a 20% down payment would be just out of reach for me.

I would be interested to hear more about the area since I, like @Julianne Kauffman, am relatively close but know little about the city.
