Check out the Short-term and Vacation Rentals forum.

Bigger Pockets is a great place for education and networking and is full of great content.I recommend that you check out the following resources:1.

I can provide support of checking in on contractors, staging rental properties, walk potential leads to give you an idea of the property in person or what the area is like, meeting with agents, and drafting scope of work for projects. 

Have the co-op take out a loan for 60% of building value, then charge buyers 20% of value in cash for each unit. 

All of those payed out in about 2 days.

You can also check their reviews online at Google, Facebook, or Yelp.

This is why I like RTR.

They should be able to teach you about asset risk, neighborhood risk, lay out A, B, C and D class areas, have stats on delinquency trends, vacancy trends, and other variable cost projections. 

I'm not sure how this "hybrid" approach would affect the cash-out refinance or if the approach is even viable at all, though.

Only in this house your mom happens to be the tenant.
