Most purchases today are from folks looking to defray the cost of their second home.  

You are probably going to killed on costs there.

You'd pull 10% of THAT to cover your expenses, and your account would keep growing..Look at your opportunity cost / alternative investments...

These costs +/- are $2,000 per year total.

35-40% is a more standard realistic operating cost. 50% is too high.

I'm not a title agent, but I presume there are fixed costs involved in any kind f services.

What cost-effective options are out there? 

So most of the time developers who pull this move, replace with a new unit NOT used.Utilities on bare dirt will cost more time/money than I think most realize.

@Alan HaleCan’t answer number 2 but financing has nothing to do with your profit I’m it doesn’t matter what you buy whether a car, home or pack of toothpicks, your profit is what you paid for it minus your costs/expensesWhere financing does come into play is it is a cost as money is not free - but it’s only what you have paid for that financing.Hope that makes sense
