Went through the analysis and here are my conclusions:This is on a 30 year fixed at 4.5%- Stop paying additional principle today:- Receive a ROR of 2.45 for the money I already invested toward principle (started making extra payments very early on.- Continue at my current rate of paydown:Receive a ROR of .98 over the life of the loanWhen you do the math it makes drawing a conclusion very simple.  

Just remind you of the investment analysis principle, "sunk cost".If you wouldn't buy the home for $350-$400K, then you should sell it. 

Definitely worth it if you can bypass the analysis paralysis phase.  

There is a rental analysis in there that is quite useful.  

Make sure you can afford a property manager in your cash flow analysis BEFORE you buy.As for seller financing you are facing the same issue.  

Be thorough in your analysis and guided by the numbers (emotions need to run secondary to hard facts).  

In your analysis and setting of metrics, do not forget to make sufficent allocations of net income to capital reserves for future capital expenditures (roof, HAVAC, sewer line replacement, etc).Welcome aboard and best of success to you.

It's a great start in your analysis and I see that you're using J Scott's analysis worksheet.

So far, my research has been limited to doing some basic financial analysis and google viewing the neighborhoods of every multifamily in my price range - up to $750k - on loopnet.  

They do a market rent analysis when the appraisal is done and apply 75% of gross rent to income.
