Quote from @Joel Bechtel: The agent I spoke with has about 30 years of insurance experience, so I’d hope she knows what she’s talking about and what she’s offering.I have another policy with Allstate for my 6-unit property, which they were able to insure for approximately $890K because the replacement cost came in under $1M.

If that isn't working out money wise you probably have other issues to address. 

How many kitchens have you replaced?  

But tax wise just here to note if you buy a 4 unit as a primary when you go to sell (if you meet the requirements) only 1/4 of the gain could be excluded under the 121 primary home sale exclusion.

Are you wanting the home covered at full replacement cost?

I replaced my old water softener with an AQUASURE from Home Depot, and it works just as well as the one I had before (which came with the house).

Tax-wise, only the rented portion is deductible, and depreciation recapture applies on sale, increasing taxable gains.

So I would caution everyone to make sure the replacement cost for your improvements will realistically cover your actual replacement cost in the event of a total loss.

The broken kitchen sink needs to be replaced.
