What happens if the roof has to be replaced?

If that's the case look into finding a handyman, and make sure to shop around for the best price.Stuff I have ran into:lost keys/lockpicking [hired]broken washer [fixed myself]shower door [fixed myself]AC clogged [hired]Microwave broken [replaced myself]holes in the wall [fixed myself] Thank you!

We don't need sprinklers here, but if we would, I'd either do that or replace the lawn with gravel or something else maintenance free.

Sometimes it makes sense to pay the gains if there are not adequate replacements.

Imagine investing in all new, beautiful finishes, only to discover that the drain pipes are faulty and need to be replaced—an issue that could have been identified and addressed beforehand.

Boot includes any cash retained or the difference if the replacement property is of lower value than the relinquished property.

Your property is fairly destruction proof, costs near nothing to maintain, yet you can charge above market rents.If your property is nicer (class B) where the carpet alone might be $6k or more to replace when the tenant spills hair dye everywhere, you won't be as happy as in the situation above.  

We replaced what we would have fixed if we were buying the house ourselves.

I haven't sold yet, I've been analyzing property to get a head start on the 45-day timeline of identifying the potential replacement property (and because I enjoy analyzing property). 

Just replace and move on. install lights.
