On the upside if you can pull it off your kids will get that 'up close and personal' exposure to making sacrifices for the long haul. 

But also the most complete (and expensive).Expensify I would say is the easiest to use and has the best interface, but it only does expenses (not income).If you're in it for the long haul it's worth considering Quickbooks as you'll eventually get used to the (awful) interface and malfunctioning rulesets, and as you grow and need more complicated things it will have them. 

In my experience, the only people who make money over the long haul in rentals like this are overwhelmingly criminals themselves, with a small leavening of police and other law enforcement officers, and an even smaller group of DIY mom-and-pop outfits like ours.

Don't know what's available in your area, but I had the same question here - after spending some time and getting prices from local installers, I found that the best option was to simply use one of them - shop around between installers obviously, but the only doors I could find available online were not much cheaper than the reasonably priced installers' materials+labor installed price, with them hauling off the old door and me not having to figure out the install etc.

Quote from @John Underwood: In my experience the people will usually move out before you have to have the constable or sheriff force the issue.well the tenant left clothes, children's toys, and a few old TVs.

@Krystle Khoo@Kris Bennett Were you at U-Haul in your past life?

Ok, I see where you're coming from, as I toyed with setting multiple accounts up.

I'm owed $1000 in back rent, and I'm estimating about $1000 for hauling away the stuff from the apartment.

I'm in it for the long haul and intend to double down if the market slumps later this year, as predicted. 

Just screen them right so you can minimize foreclosing over the long haul.
