Negotiating favorable terms like a low interest rate or interest-only payments for the first few years could help manage cash flow until renovations are complete.

Your net gain is your net sale, minus your adjust cost basis.

-Transfer the property into an LLC – This may allow me to take ownership while potentially avoiding property tax reassessment, however this sounds like an involved process-Establish a living trust for my aunt and mother – The trust would specify that I inherit the property upon their passing and provide step up in cost basis but i'm worried that the living trust can be modified to have me removed (who knows what can happen) - My mother is somewhat volatile.I would like to live in the property and my mother will live in her second property with her husband. 

Speaking to a contractor, just to remodel 3 of the 8 buildings could cost around $750,000. 

I downloaded the forms packet from the management section of bigger pockets and didn't see a template for an eviction notice.

@Matthew McleanBigger Pockets is a great place to find an accountant specializing in real estate taxation.A good real estate accountant can save you thousands of dollars by leveraging entity selection and formation, tax deductions, cost segregations, bonus depreciation and tax planning.I recommend finding an accountant specializing in real estate taxation, business taxation, financial planning and tax planning.Consider working with your accountant remotely to expand your options.I would also recommend looking for an accountant willing to work with you throughout the year.

Sounds like you need to have a relationship with a couple of good contractors, 40k for vinyl siding sounds high, what was the material cost.  

It saved my quite a bit on interest costs.

Quote from @Melanie Baldridge: 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.It’s a massive benefit 

Oh man- welcome to self management.
