Most were accommodating but one tenant decided to stop paying rent from that point and moved out in the middle of the night without notice.  

Generally, it is better to try to come to an accommodation with the senior lien holder before purchasing at auction, but that can sometimes be a challenge depending on the nature of the loan and the identity of the lien holder.

The owners that we purchased from were very accommodating when we had open houses.

Other sites like Dwolla are not geared specifically to landlord/tenant, but can accommodate bank transfers.

Ideally we would like something that accommodates us (two separate units within a structure- rather than one as it was set up) and, ideally, also gives rental income too from a rented part of what we invest into.

That and with better and better wifi, so many things aren't hard connected at all.Not sure it's worth the trouble, but conduit is the most able to accommodate the future.

Virtually all land and housing accommodations in the Commonwealth are covered by M.G.L. c. 151B, s. 4.

Soon after they moved in we made the mistake of trying to be "good landlords" and accommodated some of their requests, including a new bathroom fan. 

I do 10 to 2 and try to accommodate late check-in/check-out requests when possible (but it's rare). 

There are very few if any hotels nearby (especially with something comparable to a 4BR home accommodating 8 people).
