I’ve also included things like tubs, sinks, and other items that might need replacing.I’m focused on improving my ability to assess repairs.

And the time I spent writing the lease, screening the tenants myself, go over to the property if the kitchen sink is leaking?

Your question will be answered and debated many many ways, as there are multiple approaches to your path there.I would suggest finding a seasoned wholesaler in your area and trying to help them with their deals to learn quickly and sink your teeth in on some real-life action.Me personally, I would start on by finding SERIOUS PROVEN BUYERS, which you can find at your local REAs.

Looking in the crawl space the duct work seems to be fairly new and the plumbing looks good from a quick look under the sinks. 

As we are rehabbing all vacancies right now, we give  him a unit that has new paint, new counters and new flooring and sometimes new sinks.

Be it raise property tax or pass a levy on sales/construction or increasing fees, the local, central, state govt all want to sink their claws in you.Third interest rates are going up obviously.

I had the carpenter reinforce the corners and build a frame under the sink base so it wouldn't collapse when tenants put stuff in it.I installed RTA in my own kitchen several years ago.  

If there is water pooling around the base of the home then something is making the water run under the house....if it is pooling from all sides of the home...then I would try to make sure there was no sink hole activity under the home.

You really don't want a call saying "I filled up the sink and it fell through the countertop."

Or is this just the tip of the iceberg and I'm looking to hit something that could sink my ship?
