Then taking a percent out of the rent to eventually replace the expected large cost items that will need replacing in the life you will own the property (roof, furnace, appliances ect).

If you are renting a property, how much more can you get for black appliances over white? 

I hear this is somewhat market dependent and in some markets, they have to wait to install appliances.  

I'm in a bit of a pickle deciding whether to ..1 - vacate the currently occupied unit and take the next 1-2 months to do some minor upgrades (new roof, new exterior paint, new appliances, touch ups to bathroom/kitchen) then try re-renting it in the new year under a new property manager with higher rental prices (new: $750, old: $700). or..2 - do renovations later after weather conditions improve and stick with the current tenants who the owner chose themselves.
