Some people are financially irresponsible and don't know how to save and spend money, often they put rent first. 

If you shop around you should also be able to find a better deal on your quiet title action. 

If something goes wrong with your current house with the tenants you will be in a difficult position financially on top of the preasures of a new growing family.Babies do lot take up a lot of space so I would consider staying in your current home until you have enough equity to sell it.

For Sale by owner, Sales Agreements.I’m curious to learn what clauses or protections others builds into their sales agreements to ensure (or allow for legal action) if a private seller sells their property to someone else / backs out of your deal once already under contract.Fortunately this has never happened to me and the last 6 properties I bought were from private sellers without a real estate agent or attorney, however It could and likely will happen at some point...

To install solar panels and a geothermal heat pump in the Boston area might cost about $100K retail, which seems like a non-starter UNLESS incorporating these into a mortgage made financial sense for the buyer, and...appraisers factored this into the appraisal valueSo in other words, if the additional amount on a 30 year mortgage were offset by energy savings & programs, AND the buyer was able to live carbon-free, it seems that this might attract a savvy and enlightened buyer.
