Loan rats 28/36 what does the first number represent and what does the second number represent.
- first number is called front end ratio
- second number is called back end ration
Example for front end number conventional loan 28/36
the buyers monthly inocme is 3200 the highest he can qualify for is $896, 28% of his income.
Example for back end ration.
the buyer monthly gross income is $3200 and car payment of $150 and credit card payment of $80. Calculate 36% of $3200=$1152 and deduct the expenses= $922. the buyer monthly payment plus expenses must not go above 36%
Back end ratio
adds all the buyers monthly expenses such as credit card payments and auto loan payments.
Proration calculation
Amount to pay=how many days x daily rate
cap rate
NOI/Cost ( or value).
- Example cap rate for $1.000.000 property with $110.000 NOI is 11%. to find out how long it would take for the buyer to regain investment divide 100 by the cap rate: 110/11 =9.09 years
Calculating value
NOI / Cap rate = Value
GRM
Sales Price/Gross Rent
GIM
Sales Price/Gross Income
Compound interest calculates the _____ from the _____ plus _____
interest from the principal balance plus accrued interest
To calculate the interest
prinicipal x interest per period
for example $1000 loan over one year at 10% interest compounded is:
- Find the quarterly interest rate: 10%/4=2.5%
- 1st quarter $1000x.025=$25 add that to prinipal
- 2nd qurter $1025x.025=$25.63 add that to prinicpal
- 3rd quarter $1050.63x.025=$26.27 add that to principal
- 4th quarter $1076.90x.025=$26.92 add all together
- total compound principle is $1103.82
- Total interest for one year= $1103.82-1000=103.82
Amortization schedule/ table provides the amount of payment per every $1000 of the loan.
Example: beth bought a home for 800.000 at 90% LVt at 7.5% for 30 years.
- Find the loan amount 800.000 x.90=720.000
- Find the per $1000 amount: 720.000/1000=720
- Find the factor of 7.5% for a 30 year loan from the mortgage table -> the factor is 7.
- 7x$720=5040
