I'm trying to find a good estimate of what I can expect to pay for a cost segregation study on a single family home in Connecticut with a purchase price of $272,000.

CPA's do not perform cost segregation studies.You want to work with a CPA who can recommend cost segregation companies and know how to analyze and implement the study on your return.best of luck

If you can find 60 and three of them are within 1/4 mile of the home you are studying, then you'll get better accuracy.

STudy the market and see what others are doing.

No “tenant” or former owner language… but only if they are acting like they will stay longer than their 7 day time to rent it back handshake deal…. 

A cost segregation study allows you to break the asset down into smaller units that depreciate at a faster rate so you can take advantage of the tax benefits of depreciation sooner.

Study the market.

Then a big cost item breaks/something happens, now you're distracted from your studies worrying about a house you're not living in, etc. 

He checked with the guy that does those studies at the firm and came back with estimations that the study would cost about $3,000 and save about $5,000 in taxes over the next few years on the single family rental I purchased for $199,000 in April 2022.

If you have the time and want to become more active, you can always do that once you get a little experience.Multifamily properties are the best risk adjusted asset class according to studies and the Sharpe ratio.
