A property manager will cost 10% of $2,000 monthly rent or $2,400 a year, possibly less.Do yourself a favor and find a good, quality PM to handle this for you.

Another method is maybe talking to the Sheriff to see if they can shine any light on about move forward or at the very least be different entry point into filing your affidavits.

Are their listings detailed with good quality photos?

The Aussies always talk about rentals as Gross yield  and of course we have an appraisal method in the US that is GRM  Gross rent Multiplier.. 

Since you're only 16 with limited income and capital, traditional lending methods are out of the question to acquire property. 

@Matthew Irish-Jones yes I’m doing a moderate rehab, it appraised at $145k at (using the rental income method).

Listsource is a great site for generating quality leads.

I agree with @Weston Couch the method that you are looking for is to move your properties into a land trust. 

Method of payment for rent thoughts?

@Brendan Connolly only you can make the determination whether or not you sell your current property and buy a higher quality asset or whether you should pay off your current property or look to borrow and increase your holdings.
