What is the minimum crew size we'd need to plan for and what the minimum # of builds we might need to plan to keep a crew active in a given year.

The main living area is on the first floor.

And do we just pay for the repair to the bathroom floor, walls & basement ourselves or should they be paying for any of that too?

The house is great, great location and we remodeled it a little nicer than we originally planned given the strength of the location. 

I don’t know if it would be worth it to do a 1031 after only a year unless you’re buying both properties for much less than their worth assuming 10% in selling costs (which might offfset any tax savings over just selling the contract) if the property goes from $100k to $110k by next year your taxable gain will already be zero after selling costs.if you plan to sell soon anyway  I think I’d lean towards just selling the contract and freeing up the money, saving loan and interest costs.

Have you talked to the planning department about this?

The "Live and Flip" idea could work if you're okay with a short-term plan.

My wife and I both have good jobs that we plan to keep as we’re able to have savings that we re-invest in future downpayments.

Let’s plan for some coffee!
