I knew there might be problems when the original fellow asked me if it would be OK if they set up bunk beds in the dining room (?

There is a great solution to this dilemma; the tenant needs to go.I will just about turn a blind eye to someone with a bit of weed once in a while, but I won't turn a blind eye when they are dealing it from the property, let alone doing cocaine in the property.Unless you are sitting outside your property 24/7, you just don't know what the tenant is getting up to, and frankly, tenant paying ontime, upfront or over the top, I don't care, if he's doing drugs in my property then he has to go.And even if the junkie is just doing drugs on dining room table, what other low lifes is he associating with - and thereby - what low lifes are coming into your property, and your neighborhoods? 

It's already in the dining area.  

Previous tenant was going to convert one of the bedrooms to a dining room and cut an arch between living room and bedroom (did not finish off the arch).

It has 4 Bdrms, a HUGE 20x 30' bonus room, a great room, and a living room, plus open kitchen/dining, etc. 

I was thinking of building a great room situation in the basement with a living and dining area and kitchen all open to one another.

He stained my wood floor in the dining room and then moved the tank into the living room.  

Either way, most people spend at least that much dining out each month, it's a nominal fee. 

As for bedrooms, living room and dining room I'd say laminate flooring is ideal.  

If a tenant calls you and says her electrical outlet in the dining room doesn’t work because her lamp won’t light or her TV won’t run when she plugs it in…what type of an emergency is that from 1 to 5f: If a tenant calls and says, the roof is leaking and it’s ready to fall down on my head.What type of emergency is this?
