Would it be a good idea to take a deposit to secure the deal until the rule clears?

Quote from @Alex Patton: I know there are hundreds (thousands probably) of lenders out there that offer a DSCR product.

But if you know what you're doing in finding the properties and want a fixer upper, it's doable.I will say that the multi-family rental market is pretty saturated here though. 

Another effective strategy I use is a "Book 2 midweek nights, get the 3rd free" deal.

Modular, on the other hand, which I also deal with, you can do a mod and put it in the city limits but would cost as much or more as a stick built, more if you go with a two story.You're much better off going with an existing duplex

Honestly after I did my first deal I was in a similar position as you are.

to cut to the chase land deals normally need 50% cash down.. then lender will do the balance short term unless its ag land.. 

Why don't you share a bit more about where you are in the process, what you know about investing in real estate, what your goals are - short and long-term, and tell us a bit more about why you are asking your question here on BP?

They are a bad deal for homeowners and a terrible deal for rentals. 

I am at my wits end with what to do on this to avoid losing everything on the deal.
