Not to say I wouldn't be open to the idea but visually I just cant see a configuration that gives the current rent price I'm shooting for besides the duplex model. 

It's highly configurable and very powerful.

Since there is no place to put a drainfield in for a new septic system because of the way the yard is configured, the cost for the type of system I would need is around $30,000 I have been told.My question is, if my numbers still look good after getting a firm quote from the contractor, having a home inspection done, and the cesspit clears the inspection, would you recommend proceeding with the purchase?

Now depending on how your property is configured and how your lease is written, you can then have each tenant take care of their yard.

While you may be allowed to put X units on that piece of property, an engineer may determine that there is no practical way to get anywhere near X units based on the lot configuration.

We might be open to a living in one unit of a multi-unit property too, if it's configured right.We're primarily interested in buying in the East Bay (ideally Berkeley) for proximity to work.

If the front isn't deep enough have a u-shaped driveway with in an H configuration where they park on the side and just back out and turn to go on the road.

That being said, people make all kinds of offers that don't make sense.What's the configuration of the lot?

She said that because the bath was comparmentalized, with tub/shower and toilet divided by a door to the vanity area, and the fact that it has a double vanity and a linen closet, that that configuration would ease the pain and could be presented to a buyer as a good answer to any objection they might have.

One we did last year was a relatively newer house with oil hot water heat, but the configuration of the house meant more costs and disruption to the tenants living there.
