Many mortgage borrowers are tempted to finance their closing costs, that
is, add the costs to the loan amount. This could be attractive to
borrowers who can earn high returns on their free cash, or those who
don’t have any free cash. Financing closing costs is very costly,
however, if the larger loan increases the price of the mortgage.
This will happen if the loan amount crosses a "pricing notch point"
(PNP) – a loan amount at which the interest rate, points or mortgage
insurance premium increases. Since any price increase will apply to the
entire loan, not just the increment used to finance closing costs, it
will make the increment extremely costly.
For example, suppose financing $8,000 in closing costs on a $400,000
loan takes the loan past a PNP where the mortgage insurance premium
jumps by .25%. The additional premium amounts to $1020 in year one
alone, of which $20 is on the $8,000 loan increase and $1,000 is on the
original $400,000.
On conventional loans, PNPs in the ratio of loan amount to property
value are 80%, 85%, 90%, 95% and 97%. As an example, if the $400,000
loan is 80-83% of value, adding closing costs of $8,000 to the loan
won’t affect the price because the ratio will remain below 85%. But if
the initial ratio was 84%, adding the $8,000 will bring the ratio above
85%, so the price of the loan will be higher. On FHAs, the only PNP at
this writing is 95%.
The conventional loan amount also has a PNP at the largest loan that can
be purchased by Fannie Mae and Freddie Mac, called the "conforming loan
limit." Above the loan size maximum, the loan price will be higher.
There used to be only one nationwide maximum, but now the maximums vary
from county to county and range from $417,000 to $729,750. Since the
agencies charge higher prices on conforming loans above $417,000 than on
those of $417,000 and below, there are two loan size PNPs for every
county that has a maximum above $417000. You can find
the maximum for your county at

For a discussion of how financing of closing costs affects a refinance,
see
Finance Settlement Costs in Mortgage Refinance?
Where financing closing costs may penetrate a PNP "going up", thereby
raising the price, increasing the down payment can penetrate a PNP
"going down", thereby reducing the price. See
