I would imagine most attorneys located around the MA, NH border area plan to make more than $200,000 per year.

There's a decent jump in rate from 75% to 80% LTV which also affects cash flow...I can't imagine that anything above 80% would be feasible. 

I imagine this isn't cheap but I don't see another way.

I imagine a lot of the reasons will overlap with the previous topic.  

I guarantee you are more likely to secure favorable terms if the seller likes you and can imagine you as a great operator for the business.

I imagine those renters will fill it and then not access it much, so it shouldn't be a bother to your tenants.

Can you imagine how hard returning the wrong delivery would be?

I assume you got a better interest rate, and I know you are saving a boatload of interest. 3) imagine year 11-30 where you are cash flowing thousands with paid off properties instead of hundreds because of these lean 10 years. 4) hopefully you can raise rents at least $100 each every year and in 2 years your cash flow neutral even with preferred short term mortgage. 

I can't imagine how much extra time is spent without having automation.

Like @Kyle Mccaw noted there is significant value in goodwill and I imagine you profited nicely over this pleasant long term relationship.
