Congrats on your success so far.Some random thoughts for you:- It might be difficult to tap the equity in the rental at this time given the current state of interest rates. 

Rates were still extremely low, which made both properties extremely lucrative with cash flow.

Cash flow is definitely the biggest challenge; both in terms of finding properties to buy that cash flow with a loan on them and just company wide given interest rates and labor/material is up and, at least where I'm at in Jackson County, MO, taxes are way up too. 

With a fideicomiso, the gross income is taxed through a withholding tax whereas, with the corporation, the rate, you can deduct expenses but the taxation rate is higher.

There is a perfect recipe brewing where inventory is at an all time low, with interest rates significantly higher than we're use to, capitalized by the insane economic struggles that are going on in our every day lives.... 

Vs her current super-chill life, get's special discounts all over the place for being "too poor" and all the while can work cash jobs when wants extra, keeps her bank account low, plays the game to get here "free ride". 

To maximize your investment, use financing options like FHA or conventional loans, analyze deals based on cash flow and cap rates, and network with local investors through REI meetups and BiggerPockets.Good luck!

@Robin Simon I completed a refinance with my credit union at terms of 3/30/75 @6.85% I will have the renwal in 2026 and hoping rates come down a little by then.

If it's already turnkey that means you're paying higher rates than necessary when you could put 20% down and get a DSCR loan with lower rates and fees. 

For lending, your rates are going to be higher than if you were to buy under personal name.
