,I know I need to file taxes, do the bookkeeping, screen tenants, have strong leases, insurance, and know a bit more that the average dame when it comes to structural issues and maintenance since my parents were builders.  

When your tenant moves out if the property sits vacant for even one full month you have used up over half of your allotted budget for vacancies/maintenance/capex. 

That is a pretty routine procedure for just about everyone I deal with from wholesalers to realtors to homeowners. 

Of almost 400 properties that we manage, our average tenancy is almost 4 years, our days on the market are considerably less than most of our competitors, and our average annual maintenance on our homes (including inspections and preventative maintenance) is less than $900/year... that includes all the major maintenance as well (roofs, furnaces, plumbing issues, etc.)It seems that many investors consider property management as just a convenience, but I think that it is much more than that.

A few properties I ran are showing cap rates above 15% even with high maintenance and repair budgets and the taxes. 

They charge me 10%, but other than financial decisions over 250.00 they do everything including getting the units rent ready when a tenant moved out, placing a new tenant, collecting rents, taking care of maintenance etc.If you don't have a property management company yet, I think you have to have one to own properties at a distance...- mac

It looks good if the repairs are minimal and she has not delayed a lot of maintenance (hvac,  roof,  water heater,  etc) 

I was thinking of using a property management company to handle my maintenance issues.

I imagine families routinely move in, and are pulled in by boosters.Always been an idea I had.

But owner pays HOA / Condo / Maintenance fees.
