(In my market it varies from about 0.8% in the nice neighborhoods, to about 1.3% in the less sought-after areas)2) Based on deals you are getting from your marketing, what would monthly rent be as a percentage of your purchase price?

lol jk There are some $200K properties in the Bay, but they're on the periphery neighborhoods of the East Bay and in E Oakland - definitely not down on the peninsula.

I appreciate your help on this:First, I research the zip code and neighborhood on the internet.

Even if you buy an ideal property to begin with, things can happen that change the market, like school rezoning or a new neighborhood is built out front full of condos, etc., that makes the neighborhood less appealing.

I think it's a trendier neighborhood than where you're at, but the amount doesn't seem to be a problem.

It is rural land, but in a neighborhood with mobile homes.

According to a local rental service the average rents for 2 bedrooms in our neighborhoods are $1,050 for 2 bedrooms.

The appreciation value (or forced appreciation value), which means the property will be "comparable" to the 4 bedrooms in the neighborhood as oppose to the last comp of two bedrooms.

I'd suggest watching rentals in Craigslist weekly to get a feel for your neighborhood.

In other details that might be important, homes are cheaper here in east TN than most places so finding foreclosures from 30-70,000 that are valued at 100-150,000 seems to be pretty common and they're nice houses (not in bad neighborhoods or anything).
