Roughing in plumbing today and plumber informed me that I had no drain for the kitchen sink.

This makes your profit margin super thin, in my opinion, and one bad error could sink you.

In inspections of rented apartments, we look for leaks under the sinks, general upkeep, evidence of unauthorized pets, tenants, smoking and obvious illegal activities. 

I just need to make sure the rate of return makes sense before I sink the bulk of my money into it!

One of those having a roll in shower and lower sink/mirror for my dad.

When the new tenants were moving in, they sent me a video of cockroaches in the kitchen sink and other areas.My new tenants didn't feel comfortable living there so they are staying somewhere else until the problem is fixed.

If they bring it up I find it is a much different conversation and pieces of it sink in.

And sinks, vanities, toilets, tub, interior doors, hundreds of LF of trim, faucets, fixtures, caulk and paint, fix the yard and clean. 

Not only does the kitchen lower cabinets need replacing, there is no backing to the cabinet under the sink.

If I buy a hammer and a bunch of tools and install a sink, that hammer and the tools ians the sink is still mine but it is still tax-deductible because I'm spending it as a business expense for my business, so why isn't buying a house that I'm using as a legitimate business tax deductible?
