Unfortunately, I don't know any architects in Maryland If it is ground up you can get a head start by getting a surveyor having a boundary and topography survey done.

I remember back in the 90's, a survey of several hundred "millionaires" found only 10 or 20% had a Gold or Platinum Visa/Mastercard/Amex (status card), but over 70% of them had a Sears credit card!

I use software for maintenance and it sends a tenant survey to the tenant as soon as the repair is done and asks if it was done, if the problem was solved, if the person doing the work cleaned up after the repair and gets an overall rating for that repair.  

A long story short and a $2,000 survey bill I paid they was right (lesson #1 on trusting a tax map. lol) They have been $#$^^   @$% every since I have bought this place and we have been nothing but nice.

And there's the risk that the basic package or few packages included in the overall offer might not offer enough coverage for some homes.It might be helpful to survey your community to see what everyone thinks if you are friends with any neighbors or on a platform like NextDoor or wherever your community offers a networking/communication opportunity. 

And, I assume that it's been surveyed.

I've never heard of demolition as a solution for the problem, but it certainly seems like as much as you can do to a structure.I would find out what it costs for an environmental survey that includes soil testing.

One example was the "rent survey" from the appraiser was like $1400/mo rent and I already had it rented for $1800/mo. 

So after a couple years of his crazy bull I ordered a survey.
