The only think I hear about hers is it is difficult to have work performed on it by a contractor.

The bank will put a hold on them, so you can't just draw them out, so don't plan to need them for a while.This will cost you an appraisal on both properties to be performed by that lender. 

Most tools give you a glimpse of past performance.

these can produce good returns but best chance for success is for those that have experience in this area (I am a partner on an effort adding 8 ADUs, but it is not performing to the initial underwriting (underperforming) and it is an experienced team).good luck I get it, but not everyone has the opportunity of scale and building multiple units.

Theoretically you could sue them performance. 

@Jerry Chilimidos,Here is a list of lenders who specialize in lending to IRAs and 401Ks:https://www.biggerpockets.com/member-blogs/2810/50272-list-o...I don't know where your rentals are located and how they are performing but selling might be an option vs doing cash-out refi.I would certainly consider option C.

I had a unique perspective of how these two industries working together.While performing an inspection on a house, I got to chat with the seller and found he was a commercial construction superintendent for a large local company.

Owners mistakenly ASSUME all PMCs offer the exact SAME SERVICES and PERFORM those services EXACTLY THE SAME WAY, so price is the only differentiator – and they often select the first PMC they call!

Show a solid performing AirBNB and then punch out a list of prospecting for arbitrage and also promoting yourself as a co-host. 

That will buy you some time to get more capital together, and you know that money will be used to perform the job.
