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.

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

I do handyman work myself but I don't necessarily know all the specifics of local building code down to the last detail, etc.

I need an objective view :D Income and Expense Statement 2008 Total from rents $45,118.40 Expenses: Mortgage=$3,261.52 Homeowners Insurance: $4,200.00 Electric Bill: $267.08 Water and Swear Bill: $2,456.00 Heating Oil: Oil City: $2,185.20 Its a 5 unit building coded as an apartment.

I built a list for 4 zip codes, have a mortgage from $1,000-100,000, total assessed value between $35k-125k, and a few others.
