Take your time, buy nice brushes and go for a 14 inch roller and this is fairly easy to do. 

I live in an area with very large incomes, and low house prices compared to the rest of the country - there's dozens of cities and towns in Canada like this, so don't paint the market with a broad brush. 

I got my RE license at 18.. my first job was selling Fuller Brush door to door at 14..

Someone skilled with a roller and cut-in brush can do all the walls for that size house in like 2-3 hours.After I get a house back, I will usually go there with magic erasers, a gallon of matching paint, and a $2 disposable roller just to see how much of the walls can be cleaned up or spot-painted in a couple hours. 

@jeffreynordin to write off the entire city of Birmingham is painting with a pretty broad brush.

. $10 for a brush.

@Glen Hark, i think now they have the slate finish or a couple of other SS finishes which emulate brushed nickel texture. and yes, your biggest enemy is dents, then a scratch pad (just try to get after tenants that scratch your SS appliance, since it's still functional....)a different approach could be: check your market what is used, then step it on one notch in wow-features (kitchen and baths sells/rent homes; you have to wow the lady/head of the family)-edit: also Memorial Day is close so maybe you can get less than $400....

If it is just for interiors, just get good at rolling and cutting in with a brush.

So its just one mans experience I do not mean to paint a industry with one brush..

(some off them nice and some not) a lot off times i get asked questions that will get me in trouble with the law. unless you know the person very well he or she will just brush you off and wont give you an advice to help you with your situation.Create a relationship with your mortgage broker.
