Agency loans have very favorable terms that are not feasible for banks to compete with...non-recourse, 30 year amortization, very low rates, assumable, etc...the product has varying terms.A bridge loan would be used for a value add project to provide interest only terms through the value add period and then it converts to a permanent amortizing loan once that term is up and the property is at it's full value with rents raised and property stabilized...cash-out at that point can be feasible, lender permitting, for example if the funds are reinvested.  

I've considered cash for keys, but not sure if that would be a feasible approach here.

A duplex or small multifamily will depend on the site cost and land purchase to see if it is feasible.

I give myself enough time to do my feasibility which also gives my lender time to evaluate the loan.

Or is this something that would be feasible to create?  

I don't think I was implying that vinyl was the best option here; I was simply saying it was the most cost feasible option.

I’m at the feasibility stage and googling that service results in 4 - 6k dollars.

It just isn't feasible. 

What I would do, If I were you, is to figure out your numbers and see if its worth it and feasible for you to pay $5000 per deal to your realtor. $20k (aka $277 after splits) pays too low.

This would reduce sticker shock and your touch time.Not sure if a site is feasible (if you have enough properties to justify) but having a link to a webform where they do the pre-screening as part of the initial contact would reduce your touch time.If you are in a high rental velocity area they may be getting into other places by there time you responding or if they feel it's taking to long they may move on?
