@Marielle Walter as stated above, Boston and the closely surrounding areas are VERY competitive right now - $5-600k will be tough (factor in your renovations after purchasing too). 

This is not be a personal purchase but rather for the company I work for, so we will also have the cost to build and impact fees and such. 

Are there other factors we need to consider?

Yes but you can get an agent to aready set those alers up for you without having to pay the MLS fee.3. 

Thus, the Department believes that in appropriate circumstances, owners and managers may develop and implement reasonable occupancy requirements based on factors such as the number and size of sleeping areas or bedrooms and the overall size of the dwelling unit.

Do the math again (make sure to shop around for a bank with lower fees) and see if there is a solution to increases the value of it in a short time, so you can refinance it later after get a new appraisal after  rehabe....No deal is batter than a bad deal which will stress you out and not worthy of the time and $.  

After crunching the numbers it seems planning on a 10% vacancy rate and factoring in a property manager the cap rate should still be close to 20% on the buildings I'm looking at. 

There’s a section that says “total purchase price” if I’m purchasing the contract of the home for 100k but selling for 110k do I put 110k as the total purchase price (along with closing costs and other fees) or do I just put how much the seller gets plus all other fees exluding the assignment fee? 

It also does the late fees automatically.

We list all of our wholetail properties on the MLS via a flat fee listing service.
