While I have none in this market I have been on one realtors monthly newsletter with market analysis for over 8 years. 

Just as bad as the posts you see from time to time of the grandchild wanting to work out creative financing to buy their grandparents house below fair market value.  

You have to know the market before you build a plan and I don't think this market supports your intended plan.

Engage an investor-focused realtor/broker in your preferred market (this is not a residential realtor) and start 'tire kicking' the market and properties that fit your criteria.

Quote from @Marc Zak: In the market where I live (San Diego), appreciation has been strong and many predict it will continue to appreciate in the long term.However, with current interest rates (6% at best) and property tax (2%), the annual cost burden is 8%.Am I correct in saying that appreciation has to be above 8% annually (plus whatever my maintenance and vacancy costs are) for me to make any money in this scenario if the property is cash flow neutral?

This strategic flip leveraged our market expertise and efficient deal structuring to achieve a quick and profitable transaction.

I'd be happy to visit about the market.  

And that number depends on you, your market, your property and your goals.

We do not raise it to market rents, we keep it at lease 10% below to try and reduce turnover.

I am an experienced investor and unexpectely find myself managing a duplex myself and wondering if there is a small landlord (aka inexpensive) simple solution for marketing, background checks and lease creation that markets on zillow?
