An extra bathroom is a fantastic investment and will attract extra demand.

I would demand the Fed schedule-E, the maintenance logs, the vacancy/occupancy data ALL for two years each.In Calif, more than 15 units requires, by law, a resident, on-site manager. 

Then you need to figure out what someone might do with these properties and if there is any demand.

Make sure you understand the time demands on owning rental properties versus your business or job.If you buy in great areas the cash flow tends to be low but more rent growth and equity buildup.

Rental Demand is up and corresponding Increases are now common in Boston and most of Massachusetts now so I'm upgrading most of my apartments.

Just part of human nature (in my opinion)...My suggestion is to try to deal with people on their level -- if they seem disingenuous and shady, demand strong contracts/agreements and never giver leeway.

May be this was a mistake, but I tend to go with the ask first, demand second approach when I have good tenants.

I suggest you start smaller and in performing notes, you won't be in a position modify notes due to compliance issues and servicing and making demands will be another issue.

Also look what is the demand for your type of house that may also help you determine what decision you are going to take.

Furthermore, the supply / demand gap for affordable housing hasn’t been this severe in decades and is getting worse.
