Not waiting long enough could cause you to leave money on the table. 

The person watching down below will know when you’ve found the area that’s causing the problem.

If the driveway is heaving and causing tripping hazards that is one thing.

It doesn't sound to me like you're a professional property manager anyway - you just look after your own units - and unless you think there's a chance your friend might file a complaint against you, I really don't see the harm if it's one unit.

I feel like if you don't put in like you said mud could just be tracked into the property and cause more wear and tear inside.

Not sure what to do cause i don't want to have to keep waiting and waiting to find a deal.

I wasnt worried about damages cause the place needed paint and carpet refresh anyway.

.), it states:---A landlord must allow the tenant to renew the lease unless the landlord has good cause for an eviction under the Anti-Eviction Act.

I didn't listen and it caused much stress.

I have stopped flipping like a year ago, cause I have easier ways to make money in realestate , faster and less headaches can do alot at once.
