Before you setup your pricing, you will need to attend to some kind of startup business seminar offered by your state, for you to get actual expenses/rates for your employer tax, workers comp insurance, disability and unemployment insurance, costs that will really hurt your business if you don't use the right rates, and these may not occur instantly, sometimes 3 sometimes 6 sometimes more when you do your reporting, you will need to project this correctly as when you sign the dotted line of a contract, there's no saying that you forgot to figure in your worker comp insurance.The really tricky and optional topic is, estimating, there are a lot of things to factor in, but basically you end up of only one formula, Quantity x Unit = Total, but the encyclopedia will help you determine composition of each item, say a tile composes of 5-8 materials, not only tiles, but they generally have a predetermined amount/quantity for every sq. ft. of tile.Good Luck.

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. 

I would say my biggest advice is use this time as a pre-determined study  / saving along with screening potential markets you might move to.

If you are trying to get a HELOC on a house you recently took a loan out on, then the bank may require you to service the loan for a predetermined amount of time before considering a refi or line of credit.

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?
