Let's say your house payment is $1,000 per month. Let's say they are able to get tenants to pay $1,300 per month. If something breaks and they send someone to repair it and it costs $100 to fix it, they will deduct that amount from that months check that is sent to you.
So, 1,300 minus 75 minus 100 = 1,125
You pay your house payment for the month and pocket $125.
Every single month that nothing breaks, you would be pocketing $225
This company does an excellent job when searching for tenants. They do background checks, credit checks, etc. If the tenants are local, they may drop by their current place unannounced to have a peek inside to see how clean it is.
I'm just saying it is worth looking into rather than selling your house and taking a loss.
