Some areas can be rough and I've had break in but I try to limit them as much as possible.  

If you can give are detailed explanation of work that may help me give you a rough number but $315k is ridiculous. 

In the price range you are talking about (say roughly $180-200k), I am usually able to get really good coverage for about the $40-50/month range (depending on the particular house). 

I closed on a duplex earlier this month and I have a boiler in the basement which is inspected almost every year for the past few years, I'm curious about cost, how much does it cost to get an inspection done for this...

In one case the seller made roughly $25,000 more than if they had sold the house conventionally.But you need to fully understand what you're getting yourself into and how to protect your own interests.

Roughly one out of two is our track record over many, many deals.

They are in pretty rough shape inside, but definitely aren't bad enough off that we would scrap them.

That is still a pretty rough block, as you are on the outer edges of point breeze (farthest away from the gentrifying areas).

I'll try to make this as compact as I can:* we are getting feedback from potential lenders that our home is worth roughly $265K, with similar estimates from tulia, zillow, etc.* We owe $141KGoal - we would like to purchase a new home for roughly $365K, and keep roughly 35K for another investment. 

That is, if you know the address, the material information (e.g. bedroom / bathroom count, year built), and the estimated repair cost, you should be able to do rough comps in your head, without pulling MLS data!
