I've heard they can be done through software?

Here are some things to consider:Most investors don't need software until they have 5-10 rentals.

There are rental management software programs you can leverage at a fairly reasonable price, which is what I used to get started (I'm still a newbie).

Our firm is primarily made up of EA's (enrolled agents) who specialize exclusively in the study of tax law and representation (basically if you get audited they can defend you in tax court).

Keep track of this communication in PM software so you have a good record of it.When communication is silent there a high probability something isn't right.

Reviewing it, it seems that they are using AI type software to run the exchange.My experience so far with AI software in the tax realm is that it is a far cry from being ready for a lack of human intervention and oversight. 

My biggest concern with cost seg studies that produce a large rebate is does that flag for audit.

I would prefer something that is syndication of rental listings only vs property management software as well.Thank youJohn

I'd bet any local University has classes applicable to commercial RE investing and management, audit the course instead of attending for a grade, much cheaper

If you are not going to rebuild they will settle at actual cash value/market value minus the land.There are policies out there that will settle at cash-out replacement cost but they are rare and typically offered by higher end insurers for higher end owner-occupied homes.Every insurance company uses software to determine the estimated replacement cost of a home.
