@Larry FlanaganThe tax code states that you or a disqualified party to your IRA may not add value to the IRA through the provision of goods or services.  

For the first few projects, we used architects, but after that, my wife started doing the design herself, and we just handed it off to draftsmen who are familiar with local codes and who have engineers on their team who can stamp the drawings.There is no right or wrong answer -- whatever you're comfortable with...

Also installed a new chimney liner that brought the vent up to code.

Do I know someone who buys rehab properties in this ZIP code?

While less than 30 days doesn't create tenancy per code, you'll be hard pressed to find any  CA police dept that will enter and remove someone from a short term rental who claims rights or produces documentation.  

Realtors are trained and bound to a code of ethics.

Anyway, the tax rate code is 03-002 --click on that to see:So you'll be taxed 1.1418% of the assessed value (which will probably increase to the purchase price next year).  

I only checked 2 out 5 or more zip code  in Kent.

Hope this helps :)Thanks Benjamin for letting me know. ..lol the function works when I use my laptop but not when I use my phone.

But DON'T foirget about the part about being up to code, especially in places like CA, NY, NJ, or big cities, etc.
