Know your numbers, know your ARV, know your rehab costs and be prepared to bring them a complete analysis that has realistic numbers.And make sure to take a few mints, cause first impressions and all :)Good luck!

You did the analysis and determined what "you" thought it was worth.Your number didn't suit the seller, that's the way it goes.   

By my analysis that is a 25%+ cash on cash return, assuming the total cost of buying it and renovating it (count vacancy) is 200K, you put 25% down and you get a 5% interest rate.

I'm still in the analysis paralysis phase, mostly because I've been looking for deals locally in Boston and have been more discouraged than anything else by the market here.

I'm hoping to cover three issues in this post and will try to categorize each separately: deal analysis, Section 8, and my realtor (possibly getting a new one).

You should not be buying retail, but you can run your numbers on any property just to get comfortable with evaluation and analysis.  

So part of your analysis should have been the cost to pay one of the tenants to leave.

Also, I'm willing to bet if it's a ridiculously good deal (if you even suspect so), you could come back here and toss the details into the "Real Estate Deal Analysis & Advice" forum here and see what people think.

There is also some spreadsheets here on the site to help you with analysis and include items you may not of thought about.

Don't listen to the naysayers, don't fall prey to analysis/paralysis, find REI clubs/mentors/websites like BP and take action now!!
