This Average is calculated as taking the total Reduction divided by the number of months already paid.This is ALL Mathematics.

Based on books I've read, I've been able to identify a number of calculation to consider when reviewing a property and have come up with the following list:Risk Reward CalculationROIPaymentsCash Flow VelocityEquity My question is could anyone suggestion additional mathematical calculations/formulas I should consider as well as target ranges (if possible) based on low, medium and high costing investments.Thank you for your review and consideration.Tye

Politically (and mathematically) there is no solution to our debt issue.

So yes 50% off gross rents to get NOI is mathematically the same. 

I have found, thru a number of mathematical models I have run, that 30-70% LTV is a 'sweet spot' where rent - (piti + depreciation + expenses) = zero added tax.  

You go ahead and keep on gambling, I'll stick with the known facts and mathematics of the risk involved.There is a 95%+ chance that tank has been leaking.

BS in computer science and MS in financial mathematics - the study of math equations behind exotic instruments such as options, futures, CDO's, CDO^2 (yeah that thing that blew up the housing market back in 2008). 

Simultaneously I was reading about the business model of insurance companies (not sure why), from what I understand, An insurance company will charge monthly premiums from customers (using some mathematical model involving risk quantification to determine a premium) and make payouts to legitimate claims, Ideally there is a positive delta between the total premiums charged and the sum of all the claims paid out, That is the company’s profit.

Risk Management, tax accounting, financial reporting, financial accounting, financial analysis, financial mathematics,  macro economics, asset and debt management, business law, business strategy. 

With all that said, mathematically I agree with you.
