A good contractor can give you a best-case, worst-case estimate.

I recommend building your "core 4" (Real Estate Agent, Property Manager, Contractor, Lender) in your target market.

In your proposed situation, here is what I would do:1) Make sure you have a good/solid/reliable contractor that can actually do the work and has capacity to handle the project.2) Apply for the max HELOC and get it established. 

Some form of contract or option agreement that I was looking for specifics on that would pass muster with audit or legal around the property being a temporary asset. 

So we’d have to pay a contractor.  

You'll likely need to be there a lot meeting contractors, agents, tenants, so you'll want to be close. 3) SFH vs.

And from the other cabin owners we've talked to, it is a common problem down there to find a good contractor/handyman.

@Steven S. google Air Mac they service much of Northern NJ they have done work for me in the past and even fixed a past contractors error two. 

@James McGovern I typically only work on 1-2 projects at once because I only have one reliable contractor.
