I got part way and walked away. 

I've got an offer on two sfh in Greenville, NC walking distance of East Carolina University.

I am planning on walking through a duplex unit soon.

If we walk away we lose our 5k deposit, but almost seems worth it to me as 1.5% is significant.What would the seasoned professionals here do, what are our options? 

Purchasing a duplex, while walking through with the home inspector.

They decide their good credit is worth less than 2 million and walk away. 

Of course I was hoping for a single switch wire.This is a bathroom remodel where when I first walked in was hoping to "simply" replace the surround and plumbing fixture and swap the light fixture, switch and outlet.

the point of 1% is to have appropriate cash reserves in the long term. when you cash flow $100/door you are walking a very thin line, unless you hold additional cash reserves. as covid19 is demonstrating currently, it is paramount to be well-capitalized. 

Tuck pointing and lentels are also typically easily visible in a walk around of the building.For the water pressure and unit gut, if you were given access to tour units prior to offer and didn't, as a seller I would say it is on you. 

That train stop would be opened up for public use and would allow a new commuting option that is within walking distance of our house.
