They have two years left on the consolidation loan.

Just keep that in mind.If you can figure out a way to consolidate your families ownership to one person (you) over time, I would probably do that.

I'm running SFR models against 1 or 2 more consolidated investments in Multi Family Commercial.

How long after I consolidate will it take my credit to improve? 

It can be slightly easier to 1031 when all properties are consolidated in one entity but it's also just as easy to do a series of consolidation exchanges to get the same place.One thing that resonated with me in your post as your comment that you are 10 years out from retirement. 

Hi @Jill F.I agree with the above posts and to consolidate based on what appears to be your main concern:1. 

I want 50 units in MF because the ease in consolidated maintenance and management.  

It's mortgage free and I am trying to get info on if I should refi, cash-out, or get an equity loan (not sure on which I should be looking for) on this property for some debt consolidation.

I personally just use a simple Excel spreadsheet roughly in Schedule E like format to consolidate my various PM reports for both my local and out of state properties.

Louisville, Longmont, Denver etc some place where housing cost is reasonable......Consolidate your mortgages taking out some equity for a larger mortgage.
