Is my thinking correct that homes in highly appreciated areas won't benefit as much from Cost Seg. 

I obviously want to get the best tax benefits and write off the expenses for the house and repairs I have done.

What may seem like a benefit (NO MONEY DOWN) is actually a curse!!  

STR seems to have better tax benefits (in the right market) but is it worth it at a distance ???

But in reality, for younger people with moderate income, I actually see less benefit to financial planning.  

Rentals generate passive income, so an S-Corp offers no added tax benefit.

Britt,My firm has evaluated some smaller properties (under $500k) in the past for cost segregation, and it generally does not cost justify moving forward, since the benefits are small, and typically the tax liability on the income is minimal if any.

You can always consider doing a cost seg study on a property that you buy and that can also help with tax benefits if you cannot qualify for the real estate professional status.

I am also a huge fan of real estate and for the past 50 years there's been a way to combine both.By leveraging a Self-Directed IRA, real estate investors enjoy both the traditional advantages of property ownership and the additional tax benefits of retirement accounts, creating a powerful wealth-building strategy.

Quote from @Pamela Rivas: Hi Natasha,Here are some key points to consider about setting up a Mexican corporation:Setup Costs: $1,500–$3,000 USDOngoing Costs: $1,000–$2,000 USD/year (accounting and tax filings)Benefits: Tax deductions for expenses like maintenance, repairs, and managementBest for: Multiple properties or income-generating investmentsWhile a corporation is ideal for managing multiple properties, it’s NOT required to obtain an RFC.
