Determining whether to do a cost segregation study or not has a lot variables.

When entering the apartment, it just feels like a house full of squatters. 

In 2025 the bonus depreciation rate is 40%.This means that if you bought a property for $1M in 2025, did a cost seg study and found $300K in eligible assets that you could depreciate, you could take 40% of that $300K as bonus depreciation to offset your income in the first year.40% of $300K = $120K.You then apply that $120K to the owner’s personal tax rate to find the final amount that they can defer in year 1.If your tax rate is 37%, you can defer $66.6K.This is a big deal even at the 40% bonus depreciation rate this year.

I welcome and encourage anyone on the forum to chime in if I may have misrepresented anything, but this has been my mental model after spending countless hours running through different scenarios.I dont have a heloc personally but just curious are they all fixed rate / or are some of them variable when rates rise the interest rate rises or when rates fall the interest rates fall.   

Best bet is to try local and credit unions, possibly may have some programs for better rates.

As a percentage closing cost as percentage goes down as value increases but we will 15X to account for closing costsNo cash flow per OP.2% market appreciation equated to 30% + 15% = 45% 3% market appreciation equates to 45% + 15% = 60%4% market appreciation equates to 60% + 15% = 75%Recognize in virtually all markets the cash flow increases with hold length especially if a fixed rate loan. 

Remember, for any claim, if you can just find one case where that proposed claim does not work it is enough to prove that claim is false.So consider this.They it was told toy uo by others is inherently flawed simply by this fact:If I give you a list of 18 year old people that don't own a house... and that list is 2000 contacts large, how many deals are you going to make?

They work well for the houses we work in 100-500k.

The current price of the house is worth about $900000.
