I have about 1000 square feet to do with flooring.

The 50% rule is related to expenses, which does not include debt service, so your down payment won't affect that.If you're not planning to live in the property, you will have to put down at least 20-25%.

I need suggestions on what type of companies I should be looking into for these types of services or what type of searches I should be conducting to find companies that do these all in one services.

Tenant paid me electronically using one of the major online services.

I'm not sure the work it needs vs a 75k condo that is apartment style where you have neighbors above and on the side of you, it is on a bottom floor.

Meaning things like tile shower or fiberglass shower, vinyl floor or tile floor.  

I got a bid for $2000 for the service.

The prior owner didn't keep it safe and the moment I had the money saved up we redid the flooring (turns out the floor was rotted and that was replaced), tub surround, fixtures, toilet, etc.

I’m doing permit drawings for basement egress windows in one of my student rentals and was wondering if fixes like this were common or is it all paint cabinets and flooring?

A shell, as in just a floor, walls and a roof?
