@Kirk Brown You could try AHEAD which is an affordable housing group located in Littleton, New Hampshire and see if they might help you out.

or any buyers  I wouldnt put the first picture as the kitchen, some people might click past it and assume condo.

In my mind, it's better to go ahead and get permits (if they are required) then you never have to worry if what you have sunk money into will be recouped when you sell.Do not start working on the conversion until you have heard if a permit is required.  

Once we start buying properties, I want to scale as quickly as we can, and I don’t want to backpedal to handle things on the business side that could have been ready ahead of time. 

Sometimes it is not worth keeping a small amount of money, especially if you didn't communicate the charge to him ahead of time.

They went ahead with it (we split the cost with the previous tenants' security deposit) but found out recently that while painting in most of the house had been done, the closets had not been touched.

Now on a human level, giving them a heads up it's increasing by 70% might be worth it(that is what the 30 days notice is for too). 

If I'm out of town and can't check the house myself on the way to closing, I'll tell them to go ahead and inspect it but charge the seller as this Sch.

Add pictures of the large patio, washer/dryer and a head on shot of the driveway too, back up all the listing details you provided with pictures.

What you will find is a large number of people on both click on many homes asking for more info etc.
