Any suggestions?

Review each contract.9. 

I suggest before that, get heavily networked into your target market. namely with the older investors.

It's a fairly unregulated space (charging grandma $750 to puts around for 3 hours, after moving the old box from the horizontal sensor, which was the only problem with the garage door to begin with), so some combination of carefully reading reviews (you have to actually read them to make sure it's not 200 fake reviews), and maybe not giving them the full contract all at once, is in order. 

All the best, Steven  If you're going to do a partnership or even a joint venture agreement I would highly suggest using a competent lawyer to draft your business agreement.

Alternatively, yes you could sell, pay taxes on the gain, and use the proceeds to help your mom directly.Would suggest for you to talk to a CPA and a 1031 specialist to confirm your best move!

I’d really appreciate any insights or suggestions!

You'll probably get some good ideas here, but I'd suggest talking to a real estate attorney soon and maybe run some of these ideas by them.

I suggest 6 months of expenses to keep in cash.
