The are companies out there who inspect commercial buildings or, alternatively you can try an engineering firm. 

As a safety net/alternate exit (flip it yourself) if you can't find a buyer?

Are there alternatives to waiting 6 months to refinance? 

What is the alternative in our market?

They also have a pro desk that really helps me on orders and they even do some deliveries free if the truck passes through the area. 

Like Drew said, owner financing would be a good alternative for that if you could work out a good deal.

I was also thinking of offering to pay for the moving truck and assist with her move.

It is advisable to do your due diligence and ask about such things as how long have they been in business, are alternative assets their sole focus, are they BBB accredited and rated, are they a regulated financial institution, have they ever been sanctioned by any regulatory bodies, how many accounts and how much in assets do they administer?

I use an alternative solution but always love hearing about the experience of others.

An alternative is to partner with your Mom - she provide the downpayment, you provide the property management - and "buy out" her portion over 2 - 4 years.
