I am currently working on a mid right formula to automate the process of the letters, but because of the way Microsoft word documents transfer into excel and because a formula needs to be in its own cell it is very difficult to figure out.

what is the breakdown for the 70% formula?

I obviously can‘t give 10% of my profits.I’m curious what formula/standards others are using to calculate their charitable giving amounts.Thanks in advance for your input!

I am with @Jeff Filali on this one... his math formula indeed makes sense  (heck if you want to see real life documentary how I am executing his formula in real life simply visit my blog).. 

@Maria Marrero  Dept Service Coverage Ratio or DSCR for short, is the amount of Net Operating Income ( NOI ), which does not include your mortgage, Divided by Total Dept Service (TDS) ( usually mortgage payments, equity loans ) so the formula is: DSCR=NOI/TDS.

I have a 2 year old boy at home and the song really hit home with me.

There aren't really any formulas for this, your best bet might be to look at the pictures in rental comps other than that I would estimate the difference to be about $100 in rent for every $1000 of rental value if everything in a non-updated unit is clean, usable and looks reasonably nice.

Is there a formula  or rule of thumb Im not aware of? 

But the after 1 year value isn't making any sense to me.Just logically thinking, the equity after year 1 should be the Initial Equity + Principal Repayment which I am using the Excel Formula PPMT to figure out.If anyone could provide some help with this I would greatly appreciate it!

They do not analyze data night and day and overthink what will happen and when.They simply have a formula they use for buying properties.
