IIRC you do not need the cost seg study to be completed before the end of the year, although you do need to have your rental "in service" before the end of the year.

My wife and I did this about 13 years ago we had the chafa program I didn't know this was still available to first time  home buyers it is essentially down payment assistance you put the majority of the down payment into a 2nd loan 30year fixed with means your mortgage payment go up like 100.00,  we then payed off that with the tax savings the following year..don't quote me I am not a advisor .

Thank you in advance for your assistance, I appreciate it. 

Utilizing the same approach can can assist with for-sale housing as well where you can decrease DOM and move your inventory quicker, thus saving on carrying costs.

Pick a market and begin to study it. 

Hire an assistant to screen tenants, show properties, and delegate maintenance calls to above mentioned trades... basically handle it all early on and then build into employing those who manage your properties?

I'd certainly recommend doing some kind of environmental study given the chemicals and such that could have been used there but more-so I'd be curious if the city wouldn't have a testing requirement to redevelop. 

A good PMC can assist with all of that for a Placement Fee.NEVER trust a real estate agent to do your screenings, as they have a conflict of interest - they won't have to deal with any tenant issues once you pay them their commission.

I have been in financing for 35 years and am living proof of what I am stating, plus have coached and assisted folks all over the country on the concept, to the tune of several billion dollars of loans. 

A Cost Segregation Study was performed on a 2-story, 5,237 square foot Office Building located in Louisville, KY that was built in 1946 and purchased by its new owners in 2021.
