Would love to be able to underwrite a property quickly and efficiently.

many people don't necessarily have the time or skills to do their books*REI specific tax efficient advice to include business structures, 1031, depreciation, deductions, etc.  

The Unilin 2g locking system is one of the most efficient ones on the market.I 100% agree the the subfloor/ underlayment/ substrate being attached to as well as how  it was attached to the builder floor(naturally we're not talking cement) is usually the problem in a failed installation. 

Stick to it.Real estate investing is tough and those who say it isn't tough either have never bought a property or are trying to justify how much time, money and energy they’ve spent to get the meager success they have.

If seller won't extend, cancel the contract.6) If contractor bid too high you can either cancel the contract or renegotiate the price.This is more efficient for everyone involved. 

In other words, you lose the efficiency of being able to turn over the entire property at once.

Alternatively, you could install energy-efficient fixtures and appliances to help keep utility costs down for both units.

Also, 10k is high unless redoing all the ductwork or a really high efficiency heat pump.
