Hey Wade, you'll need to get a lot more information to properly analyze this deal.  

If numbers work, everybody would buy an already rehabbed property, It is not easy ti find.

This means easy to find answers online to most questions. 

There shouldn’t be any extra charges for mobilization or other upfront costs since he is so far into the contract.If not, then having given proper notices and record retention is important in “termination for default”.Otherwise, you guys need to figure out how to agree to part company.

We initially set up our VRBO accounts to Instant Book which didn't  give us the opportunity to properly vet renters.

Especially if the PM properly vets the tenant then the 10% of the rents is plenty, IMO.  

But this also means the tenants are more likely to use the machines and possibly drive up the cost of utilities and the wear-and-tear on the machine.There's no easy answer.

Have the correct insurance to cover STR activity in your home (Proper and CBIZ are the two major players in that area) AND have an umbrella policy in place.  

Typically, are MEP construction tasks a difficult project for contractors in this type of situation, or are they easy? 

You will find a strong network of Baltimore investors here.Your question is not an easy one.
