Its currently occupied and the rent being charged is way lower than comparable houses in the area.

Curious - what's the best way to compare rates for jumbo loans?

My wife is a high-end residential interior designer (Projects  $1million and up) and the esthetic you have in this house is comparable to her style of design. 

You can't compare that cash flow vs a non-owner occupied 25% down cash flow. 

I know this is not a traditional method but it works for me because to collect that money up front would pay for my holding costs for 2 months regardless of wether or not they come up with the rest.  

What are the vacancy rates, comparable rents, house prices; become the expert.

I guess ultimately you'd have to crunch the numbers and compare, but in my head that's what makes sense.

I know I can’t get traditional financing on places where there isn’t flooring...they won’t underwrite the loan.  

@Amanda M LairdA residential property is valued using recent sales of comparable properties.

I'd deduce you're referring to LP side and want to invest as an equity partner in a syndication since you're comparing it to crowdfunding platforms.
