To make the list, an individual agent needs to sell 50 homes/$20 million in volume, or a team needs to sell 75 homes/$30 million in volume.Im in the top 1% of agents nation wide, and one of the top agents in the DC metro area, and I do not even qualify to make the real trends list.  100 homes in a year easily makes their list. 

Those big windows in the shower are very poorly placed... they ALWAYS end up leaking at the sill creating all kinds of wet rot inside the wall, plus they're a privacy problem.We replaced them with a "gun slit" approx. 30"-48" wide and 6"-10" high, centered in the wall.

This isn't something I would leave to Bigger Pockets forums the laws vary widely by state so it would probably be best to look up the law or talk to a professional in your area, (not over the internet) who knows what they are talking about.

We were very careful to disclose EVERYTHING with the buyer so that they were going in eyes wide-opened.

Finding local foreclosures is actually something else I am interested in figuring out but haven't really looked into yet - but I'm definitely not seeing them in the same place.I was really considering buying a parcel at this auction purely for the experience, but by the time they removed the ones that had been redeemed before auction day there were only I think 3 that were big enough to legally build on (and not even usable if rezoned somehow, just like 4 ft wide strips of land between 2 houses and such).1 of those was commercial, would have required tons of tree clearing and excavating to build on it an all the engineers, applications, and hearings involved with that were intimidating for me... that was the only useful one I could've afforded. 

So 6 48ft wide lots make the width of the north half of a block, and another 6 make the south.

Now my question is would it be best to spread this across a wide portfolio or would it be better to put it in one or two large investments?

When gas got deregulated in many areas of the country (quite a few years ago) many were happy because now they had a wide variety of companies to go with as their source of gas. 

Me , I would just bring it to the front corner of the house , 2 cars wide and a walkway to the front steps 

We do still have a big disparity between certain areas (seacoast and the southern part of the state in general) and the more rural areas and much further north, in terms of how quickly stuff sells/market activity, but generally in NH the rental market is very strong, both for SFR and apartments, bolstered by the real shortage of affordable housing for local workers to buy.
