If you have hired a specialist to perform a cost segregation study of your real estate property, they will likely use one of the six most common methodologies recognized by the IRS.

This is common for that build time frame.

@John BerjIf cash flow is a top priority, factor in HOA fees (common with new builds) and confirm rent comps to ensure the numbers work.

How are you managing your properties in that area given that property management company seem to be extremely unreliable and seem to go under quite frequently 

This could be a huge problem, as the "the rent is too damn high" people will be extremely upset with huge surges in the cost of living, felt acutely in some major metros.3) 2027-2029 should see a return to a more normal inflation adjusted rent growth curve, with the caveat that if supply continues to remain relatively low, we could see national rent growth outpace inflation in these years as well, so long as interest rates remain high. 

In fact, I don't think you should charge ANYONE because it was YOU who accepted that the switch is located in a common area. 

You have a skillset that could be extremely useful for quick fixes and landlord issues and from there you can bridge relationships and partnerships to enhance your knowledge of real estate investing and couple your skills.

They are far more common now and harder to find models without but:1) these add cost to the purchase price2) they don't bring a lot of value3) they can leak or detach and damage the propertyI own around 50 doors and I cap off the line at the wall or in the basement with a valve and a cap so the potential for leaks is 0.00001% :-) 

I'll throw in my 2 cents on common differences I've seen in my career:CDFIs - Because of their subsidized financing structure, they have the ability to be a low cost lender (and sometimes provide grants).

additional challenges are the inventory shortage and good contractors being extremely busy.
