You don't want to be responsible for buying her a new flat screen tv because you didn't take pictures and store it or whatever your state requires.If she didn't leave a forwarding address, send to the last known address (the property) via first class mail and then collect that letter and keep in your files as proof of notice.

In a year you will have 7200, enough to replace some HVAC, maybe a flat roof.

So do you get a flat rate or a % fee right now?

I am currently paying a flat 6.5% fee, but haven't been happy with the results.  

If you sell a certain amount with Keller Williams they stop taking commission on your sales so if you become a high level producer you start being able to keep a higher percentage of your overall commissions every time you sell more.If all you want is to be able to buy / sell real estate and save on commissions then you probably want to find a brokerage that has a flat fee per closing as a brokerage fee instead of a %.

However, if you are talking about properties that are not listed, that is a different game altogether.

I am talking about taking a flat commission of 5K on a 45K house to represent the additional time and energy required for a home that cannot be financed and is going to require a specific type of buyer.

I'm new to BiggerPockets and new to investing altogether!

I aspire to eventually buy and hold enough rental properties to generate a passive income of $10,000 a month which would allow me to leave law enforcement altogether.

Or it could go up and then stay flat.
