I walked through a couple of rehabs with a local contractor and it seems like those number matched right up with what he was doing that type of work for.

By filing a petition for bankruptcy, a person creates a bankruptcy estate.The bankruptcy estate is a distinct taxable entity—separate, that is, from the debtor’s estate that may retain any property exempted from the bankruptcy proceedings.Under the federal Bankruptcy Code, the debtor has no claim to this new creature of law, the bankruptcy estate.

I don't plan to test that definition too much and plan to replace by two year from the Fire loss just to be sure.There is no call for a QI which is good because insurance payments and mortgage payments alone is sufficient nightmare.There doesn't seem to be any requirement for mortgage matching like the 1031.The only issue is the Replacement property must be same or greater than the loss property gross cash obtained.As a side, in such cases insurance checks are written to the insured AND the mortgage holder. 

You might consider getting a laptop to match so you can share apps a little easier.Specs: 8GB of memory, 256 GB of storage, i5 (8th gen processor or later) and a 14"+ screen size is a good place to start if you are going to download property software and store a lot of property photos on your system.Chromebooks don't have an operating system (meaning you don't have Microsoft Windows, so no excel, word, PowerPoint, etc).

But in the end I need them to match the quality of the unit, we typically spend about 40-60k on a single family rehab and I don't want to top it off with some ugly old appliances.

If you can match their date, it’s a win/win!

So if the two units are roughly identical the you're good to go.You want to think of your replacement duplex as two distinct properties. 

With four of the top eight MSAs in the nation (Houston, San Antonio, DFW, Austin) in terms of improved or bettered job growth, GDP, and unemployment since 2010; you can find an investment that matches your financial goal @Ashish Yadev

So you must also be comfortable loosing money if you do not at least match those increases.

Might be a distinction to make between the different parts of the value chain to answer your question.
