This is also assuming your figures are accurate on the others.

Your numbers are accurate to the dollar. 

I'd also suggest running some for-rent ads, to see what type of response you get.It's notoriously difficult to accurately predict ARV on these types of properties, because they're so niche, and the market for them is usually completely different than the market for more standard properties...For instance, a lot of lenders won't provide a mortgage on a property for less than $100k--and if that's the case in your area, that would mean that the only potential buyers for the property are cash buyers, which makes selling the property more difficult.  

Providing this information upfront can help to ensure that the appraiser has all the necessary information to provide an accurate appraisal.Overall, by focusing on cost-effective upgrades and providing the appraiser with the information they need, you can increase the chances of achieving a favorable appraisal that will allow you to be front-end profitable on your rental property after refinancing.

Also, most of the phone numbers provided with the Seller's info are not accurate.

How accurate would you say the data from those two providers is?

This other GC of course needs to see the full set of plans to give me an accurate quote.

Also the point about lenders not doing anything about performing loans if there is a title issue is not accurate.

But I’m thinking in order to use passive losses from other entities (multi family, SFR’s, etc) I would also have to show material participation in those activities in addition to the REPS, is that accurate?  

It won't be 100% accurate, but it will be close enough.
