Yup hearing 3% down payments are becoming very common.

But the connections for utilities are still available, water, septic.

I got my list from listsource.com and figured out what parameters I wanted to use via a lot of research and common sense.

Is this common? 

As another alternative, you could sell the house, take your $500,000 excluded capital gains as your primary residence, pay your capital gains taxes (both federal and state), and buy your new property utilizing a small purchase loan or even reverse purchase mortgage to make up the difference? 

It is 6 months now and I get many escuses (Contractor from Insurance does not do the job, Contractor went broke, Seller is meeting with attorney General...)Is this a common situation ?

Some people may balk at buying home with a ROW ON their land, but it seems less people have an issue buying a home that has a right of way TO their land.It's fairly common to have them in Maine so provided the road is in good shape and generally out of site of the house I wouldn't be concerned.  

Per your question, no getting around the registered agent law in the Burg.This is really common in most areas.

Some common mistakes are trying to go cheap, not vetting out contractors, paying contractors too much up front, not having contractors sign a contract when you accept their bid, not having enough of a cushion for unexpected repairs (there will always be something)

They may sabotage the sale by complaining about the HOA or that the cabinets are cheap or utilities are expensive.It sounds like your tenant is a good one so it may not be a problem.
