Your sister could be added on as a non-equity employee and issued a W-2 salary for services provided. 

I just depends on how much you can achieve and how the market is. 

@John Moran,There are number of active investors as well as service providers who are frequent contributors on this forum.

A property management company is a vendor and I wouldn't give equity in exchange for vendor services. 

So the only question is, does the Market Rent for that location and Type of Unit cover the HOA, plus Debt Service, plus whatever other Expenses need to be paid..Because if it doesn't, the Landlord is in for a world of hurt!.

College should not be viewed as a barrier to achieving your goals, but should be a pathway to better achieve your goals. 

I hope BP helps you achieve your goals!!

Replacing a faucet is a fairly quick and easy task for a plumber, but they'll charge one hour of time and sometimes there is a longer minimum for any service call. 

The landlord-tenant relationship is simply not all about bloodless logic and the simple exchange of money for a service or product.

This will determine not only how passive or active you want to be, but it will also will help you to determine what type of strategy you should implement to achieve your goal.
