I have a bachelor's in Applied Mathematics and am employed as a junior software engineer.

I am a high school mathematics teacher in Dallas, TX, but take advantage of the lower cost of living in Irving, TX. 

And on and on and on.Assuming that you have absolutely identical tax years in 2024 and 2025 (which is never really the case), you usually win mathematically by spreading your sales (or any income, for that matter) over multiple years versus receiving all income in a single year. 

[Note: There appears to be a defect in the parser for the forum which prohibits one from using the mathematical symbols for "less than" or "greater than" in {HTML} formatted text such as bullet lists. 

Not to plug him but I read Dave Ramsey's book on personal finance and used the snow ball theory and it was amazing how fast the balance of student loans go down when you really focus on them, its not the most mathematically efficient way but very satisfying for human emotion for sure.

It absolutely DOES work and this can be proven mathematically.

While there are differences when it comes to investing in Mexico, the mathematics are the same on both sides of the border!

Leverage and invest at 40x $100 000 properties ($20k down + $5k closing cost, 30 yeas fix rate loan) with a return of 10% where you have better asset protection (my keeping lower equity and higher bank position), you are hedge against inflation (agree with me, in 30 years $1 000 000 purchasing power will be less compare than $1 000 000 today) Here is how looks mathematically:1. 10% on $1 000 000 (10x $100 000) = $100 000 / annually - No interest tax deduction- No loan paydown benefit2. 10% on 1 000 000 (40x $100 000) = $400 000 / annually - debt service + full tax benefits+ loan pay down+ hedge against inflation for 30 years+ better asset protection (by maintaining lower equity  position)   + (not guaranteed of course) if appreciation happens, it happens on the all full asset amount, example:If appreciate 10%:In case "1" you will have 10% on $1 000 000 = $1 100 000In case "2" you will have 10% on all 40x properties (40x $100 000 = 4 000 000) = $1 400 000As far as cash flow, as long you buy "right" CAP 8% and higher you will have stronger cash flow on leveraged asset + all additional benefits.

Mathematically the IRR calculation requires a closure of the CF loop.

I can PROVE it with mathematics that SEO is fact not opinion.SEO and Google is a computer algorithm.
