Some facts of the house:Location: Nassau County, NY, Town of HempsteadYear built:1929Purchase price: 290,000 in 2013Condition: AverageLot size sqft: 5000Livable sqft: 760I'm seeing several houses in my zip code that have been demolished and rebuilt into new houses with the maximum allowable livable square footage selling between $1.0M- 1.2M.Which is a better option taking into consideration, profit and capital gain tax (assuming my household income of 80K)1) Should I sell this house as is at $450K2) Demolish this house and rebuild it without taking out a loan.

Also unsure about how taxes would play out (see CPA). 

Having a mortgage on that home might change some of the answers so just be prepared with how much the property is being rented for, what the taxes and insurance amounts are when you reach out.

These include fix & flip and DSCR rental program that don't require tax returns of W-2 jobs, but rather uses your credit and property income to qualify.

I'm focused on the STR strategy as I would like to benefit from the tax advantages that it offers but understand it may not work out.
