I would love to find a lender who would let me personally co-sign on a loan when the assets are in an LLC.

Lots of nice lakefront homes in Nevada, California, Utah, Colorado or Idaho. 

More specifically meaning if this was operated in one state on the west coast (Colorado) could you apply for a mortgage for a property on the east coast (Connecticut) and meet the mortgage requirements for pre approval. 

If the primary borrower on an fha loan has little to no income (say a student just finishing school), can a co-signer or co-borrower still qualify them for a mortgage even if the co-signer or co-borrower is a non-occupant?

If you’re currently renting I would buy something to live in/house hack and have friends/coworkers move in with me and pay me rent.

Good news is you’ve hired a pm co, and this is their mistake to fix.

It is a elderly mom of a friend/coworker of my wife.

I assume you'd like to be off the mortgage of any house you no longer own, so she either qualifies with or without a co-signer, uses her share of liquid cash to pay off the mortgage (if applicable), or one or both of the properties are sold.This is where your divorce attorney and tax advisor come in. 

Find a partner willing to co-sign and who’s in need of an apartment to rent?

Some general contractors do certain trade work in house and other smaller guys sub out a lot of things to keep their overhead tight, because they don’t have to carry workers when they don’t have work.
