At first blush, it doesn't seem cost effective to have full cost segregation studies completed for my current portfolio.  

Quote from @Michael Vacha: @Stuart Udis accidentally posted this on the wrong response but I want to hear your thoughts as well  I agree that events do happens, that's why I am learning to midigate the effects of that with underwriting future expenses into my evaluation, while not perfect it will allow me to have reserves to handle those things over time and as I reach an acceptable cash reserve for each deal I can re apply that percentage of monthly cash flow to anything and when I use the reserve build it back up.

What was replaced, who installed it, what warranty applies, and whether that warranty is actually usable when something fails again.Early on, warranties were effectively useless because:Paperwork lived in emails or invoices that no one could findVendors changed, disappeared, or denied responsibilityPMs or VAs didn’t know what had been installed three years agoNow, everything is standardized:Approved materials list by asset classPreferred vendors tied to specific scopesWarranty info logged at install, not at failurePhotos, serial numbers, and install dates stored centrallyThe key insight is this: warranties only matter if your system can surface them at the moment of failure.

If the tenants are effectively moved out, putting the utilities in your name and maintaining a minimum heat setting reduces risk and removes uncertainty.

This means a portion of the previously taken depreciation will be subject to taxation, effectively lowering your adjusted basis in the property and potentially increasing your taxable gain at the time of sale.

But the worst side effect so far is missing out on a lease opportunity from a good tenant.  

The HOA consists solely of the two unit owners and covers the master insurance policy, so it would effectively be dissolved in a coordinated sale.I’m open to input from:- investors who actively buy duplexes in Austin- brokers experienced with coordinated duplex sales or reduced-commission structures- owners who’ve sold in a similar situation and can share what worked (or didn’t)The goal is a clean, efficient exit, either individually or jointly, and I’m looking to sanity-check pricing and structure before moving forward.

To segue into @Collin Hays point about having good insurance, the most effective way to achieve that is by operating the business well and avoiding conflicts in the first place.

So from what I am getting, this would probably only be cost effective on a larger building if the property is existing but on new construction it is a good idea to integrate a cost seg analysis?

How long are you going to need the loan to be in effect?
