Purchased for $139,999 using a mix of cash and hard money, we revamped it with modern updates, including a new kitchen, flooring, and fresh paint.The property rented for three years, generating steady cash flow of $450/month.

Failure to clean up pet droppings willresult in a service call (Pooper Scooper) billed to the tenant.

I'd personally say pulling your water heater out and replacing with a wall mount on demand one, would be worth the cost to have in unit washer dryer if you are staying there or renting it, it would be worth it.its always worth doing the big stuff well and correct even if you are cleaning up after someone, the long term hold always prevails, its just a little frustrating front sometimes, but hang in there!

What is the flooring material?

Start with one that might need some clean up and go from there.

I would consider getting out of property management and getting into cleaning IF you think they are doing better than you .
