Once all the work was done we rented the home for a couple years and then sold.

If you're dead set on that path then I would recommend getting a google meet with the person and give them as many advantages they have to using you as opposed to a property manager ex: guaranteed rent, more exposure, and less fees (use chat GPT to get a good list).I would emphasize the fact that it is much easier to get rent, and there is less risk to them in the sense of cash flow.

I purchased a 4 unit in Dec 2021 in Pt Loma (Worth ~$2.5M then, now worth ~$3.4m). 

The borrower can then legally sell the collateral in order to recuperate their money that was lent.

So if you can get it paid for then why not 

Then it sounds like you have your mind made up then right?

Until the lease ends and then the legal notice time in your market has passed.

I wouldn't feel good about convincing someone elderly to sell to me and then turn around and wholesale it. 

I used them all as primary homes then moved and rented them out.

Hard money then refi residential 30 yr How did you add value to the deal?
