Have enough reserves and patience and build a portfolio of at least 8-10 properties to get some kind of predictable average return.

The inspector has just confirmed it will need a new roof.

@Dave FosterThank you very much for confirming.

And capex is probably $300 per unit for ongoing replacement reserves, on top of the capex dollars I raise at the time of purchase for upgrades and deferred maintenance.

Hold reserves for projected maintenance, capex, taxes, insurance, and other projected costs.True cash flow gets paid out to you as the owner.

I would consider the following (which you may have already done):House rules say no gatherings (penalty of $X per person if violated)House rules say quiet hours are 10:00 PM - 8:00 AMIf profile has no reviews / not verified, require they confirm the # of people who will be at the property & agesUse a noise monitoring system like Minut or Noiseaware (disclose in listing)Use exterior cameras to monitor driveway (disclose in listing)But at the end of the day, there are still bad guests who will get through and sometimes you just have to file a claim, kick them out, apologize to neighbors, and get the place ready for the next group.

I have about 20,000 for a  down payment and another 10,000 for reserves.

CAPEX reserve is around $400 a month (10% income).

You need reserves to invest in RE... so if you don't have the down payment how will you take care of a major repair?

There maybe some reserve restrictions nowadays, etc.
