Is there other market wide metrics that apply here? 

I would really like to hear from someone who has deployed their tactics and completed a deal to get a view of the full range of experience with them.

For lower value flips, 200 - 300k, we stick to that range as the projected profits doesn’t have much room for an inevitable rehab oh-$hit.

When a builder builds a new house that meets my requirements, in my price range, I move out of my duplex and into that new house. 

Options like our partner Baeslane’s free online rent collection platforms, payment apps, and ACH transfers are convenient for both parties, but traditional methods like checks or cash are still widely used.I’d love to hear about your experiences:What rent collection method do you prefer and why?

If you want more cash flow deals you may want to look outside of Boston and test out some new markets where you're hitting closer to the range of returns you're looking for. 

I say Keller Williams because I used to be an agent there and I know they are a large brokerage world wide. 100% of $1,000 commission is still better than 100% of $0 commission. 

SB9 was state-wide, so it's up to cities to implement.

I would do some market research on top-growing cities and determine which of those cities are within your price range and cashflow goals.

I would think it would rent well in the 1,350-1,450 range, above that it will be tougher.
