A word about mortgage payments (PITI)
[OFF] Turns the calculator off. The unit also
has an auto power-off feature which turns
the unit off after 5 minutes of non-use.
A mortgage payment will include the mortgage
payment principal and interest, in this case
$787.22. It will also include the monthly real
estate taxes and insurance payment (Divide
the annual rate by 12 to get the monthly rate).

For Example:

Annual taxes at $2,400, and annual insurance
at $600 = $200 monthly tax payment + a $50
monthly insurance payment. Adding these to
the total payment of $787.22 give us a total
monthly payment of $1,037.22 (This is called
Principal + Interest + Taxes + Insurance or PITI.)

How to compute the mortgage
payment you can afford
Industry guidelines indicate that a consumer
should spend about 28% of his monthly
income on housing. If your combined
family monthly income is $6,000, you can
afford a mortgage payment (PITI) of $1,680.
(Other payments. like credit card and car
payments, installment loans, etc., should not
exceed 36% of your gross family monthly income.)
