Don't tell the tenant you are cutting them off after this just see how it plays out.

And if they are fully on board, then offer your services as an operator and take your 20% or more cut plus the cleaning fee. 

Second, they can make unnecessary repairs just to cut their rent down.

They looked good on paper, but the problem was they couldn't close and I wanted to rent the unit.I'll admit it really cuts down on the amount of applications I receive, but the "signal to noise" ratio is much more favorable for my time invested.  

Are you saying 1) get a check from the money person 2) deposit into my account 3) write another check to the real estate investor 4) when I get the money back from the real estate person, take a cut and write a check back to the money person?

But I highly doubt it because it would have to comply with all the state requirements and there is quite a bit that goes into that and lots of liability too and then they would take their percentage cut.

I probably do mine every 6-12 months, tops and I own the place.I would do all the paperwork and notices and invoices and make sure the tenant knows that next time they will pay the cost and any/all cost associated with any damage the neglect causes.For a good low maintenance tenant, I'm going to cut them some slack for a pretty unrealistic maintenance itemAnother reason why local landlords just do the filter themselves and use it as in excuse to inspect the property every couple of months

Id just cut bait now.Do not sign a new lease, just give them the proper notice in your state to move out, most states are 30 days.

If you're relying too heavily on your local MLS for deals, it's going to be VERY difficult in a lot of markets to buy correctly because you will be competing with seasoned cash investors that are able to cut costs.Relying on brokers is not the best bet either, as most of them are retail-focused that don't understand the economics of the investor game. 

Almost all taxpayers are impacted in some way by the new tax law introduced as the Tax Cuts and Jobs Act of 2017 (TCJA).
