I am only asking because I have seen this work before with people who have a large amount of rental properties, and would rather someone else manage their properties and still collect 80-85% while they are pursuing other interests.

If not, you may want to consider a refinance on a property to hold you over for a little.Are you waiting a couple of years till you collect retirement income(social security, pension, etc), then maybe doing a refinance until you get to that period of eligibility to collect.

She collected rent by check sent to her address.

Collected $1,800 on the property within 32 days of owning it.

Yeah there’s no appreciation but I’m ok with just collecting the rents every month

I wouldn't lose too much sleep over it and/or try to collect any more than that.

Collecting rent and answering the phone is easy, but getting the right handyman, that you trust to fix it right and for the right price can be trickier.  

I collect it.

You get to decide what to do with that $100k now rather than wait and collect it over 16.5 years.Next, if you can scale your real estate investment through value-add aka BRRRR, then you can really grow your REI biz. 10 units at $500/door net cash flow = $1M worth of cash in your pocket. 100 units at $500/door = $10M.Then, every year, raise rent $50/unit.

Vacancy/collection loss should be estimated based on market information.
