Hopefully, since they've only been in the house such a short period of time, there really shouldn't be much damage or even wear-and-tear.  

Could damage bookings for whatever time window you leave available.

It's the wrong time of year to seed a lawn in my area.I do not remove existing satellite dishes because it could damage the roof.

This way, we continue to have cash flow coming in, and if we happen to have a bad contractor or one or two units and/or some permit/regulation related issues, the scale of the damage won't be too overwhelming. 

This means telling them you own the property and if they don't pay the rent or damage it they're directly hurting you.

I am in NJ as well, very expensive (I just wholesaled a 2 family with fire damage in jersey City for 600k) One of my clients got me into the TN market, I have a few single family rentals there, all purchased under 100k

We were asked by our neighbors if we would rent our FL home for a couple of months as their home was severely damaged due to a water line break.

We had water damage on property that required 20 days of repairs and replacing flooring throughout the unit with much nicer upgraded material.

@Connor RileyI've been watching TV court cases, plenty of them involving tenants leaving with damages.

If a house is in good shape, and the owner wants to maximize the sale price, they will.You get the 20%+ from finding distressed properties: maybe the house is damaged and the owner can't pay to fix it and a bank won't lend a mortgage on it.
