Depends on how bad it is and whether or not the numbers make sense.

@Isaiah Hall this is going to depend on your persona financial situation and they type of deal.

As mentioned above, depends on the county/city.Davidson county - Nashville for example it's not really hard to get permits for a standard single fam house.

That said, there are strategies to minimize the tax impact depending on your timing and future plans.

Bonus Tip: Create a "Daily Log"My contractor (or I, depending on the day) writes down what work got done, what materials were purchased, and if any payments were made.

For example, if you want to find out whether you can claim your mother as a dependent or what records you need to keep in order to prove your charitable donations.When we deal with controversial and highly technical topics such as the question you posted  - you need professional expertise.

My A+ managers here in Nashville charge 15-18% depending on the type and number of properties. 

If it's only light cleaning, and no bad food debris or piles of wet towels, etc, they may have the cleaners come the following day depending on the schedule.Over the last maybe 6 months I have started to notice an increase in the number of guests asking for extremely early check ins.
