They guys said that before you make any moves, first determine how much you would like to make that year from real estate and then work your way backwards from there to reach that predetermined goal.

I agree with the article since every web web page that references the maximum charge landlords can charge states that the fees have to be actual costs and not an arbitrary or pre-determined fee. 

By you getting higher monthly "credits", will increase your ROI but will also, of course, help you cover all of your expenses, assuming that you have a pre-determined purchasing price in X amount of year that the tenants will buy from you. 

In most construction Basically what I am asking is Does the #, size and total amount of opening space per square foot in regards to windows on houses accumulate to a pre determined number or is it based on every house specifically designed with window location and variation in mind.How do they figure out how many windows and what sizes?

When I see figures like that, I suspect that the Report has been rigged by someone using pre-determined desired outcomes, rather than cold hard correct analysis. 

Searching for confirmation of pre-determined biases.

TLDR: What agreement should I write between my grandmother and I so I can take over her house (mortgage payment, agree to buy the house at a predetermined cost), while we keep in her name and then finance/buy it at a later time?

Often times we get emotionally over-optimistic about a particular property and we lose sight of the potential downside.I'm not sure if youve ever heard of a Monte Carlo simulation, but what that does is take your projected numbers and runs them through a predetermined number of simulations, sometimes over 1 million different scenarios if you wanted it to.
