(i) Determining “value”

(A) For purposes of calculating LTV, TLTV and HTLTV ratios For purposes of calculating LTV, TLTV and HTLTV ratios, “value” is determined as follows: Determining “value” Mortgage offering or characteristic “Value” is… Purchase transaction Mortgages The lesser of the appraised value of the Mortgaged Premises as of the appraisal report Determining “value” Mortgage offering or characteristic “Value” is… effective date and the purchase price of the Mortgaged Premises. Note: For newly constructed homes, multiple contracts may be combined to determine the purchase price (e.g., the purchase contract for the house and a contract to install a swimming pool may be added together to establish the purchase price).

(B) For Mortgaged Premises located in the State of New York For Mortgaged Premises located in the State of New York, solely for the purpose of determining whether mortgage insurance is required or should be canceled, the “value” for Loan Product Advisor® and Non-Loan Product Advisor Mortgages is the appraised value of the Mortgage Premises as of the Note Date. For Mortgaged Premises located in the State of New York that are purchase transaction Cooperative Share Loans, solely for the purpose of determining whether mortgage insurance is required, the sales price of the Cooperative Interest may be used. See Section 4701.5 if mortgage insurance is required. This definition of the value of the Mortgaged Premises located in the State of New York applies only to the above-stated mortgage insurance requirements and is not applicable for any other purposes under the terms of the Purchase Documents. See Chapter 4701 for mortgage insurance requirements. (ii) Calculation of LTV, TLTV and HTLTV ratios for Loan Product Advisor Mortgages Loan Product Advisor calculates the LTV, TLTV and HTLTV ratios based on data submitted by the Seller. Note: For certain Loan Product Advisor Mortgage transactions, Freddie Mac may accept the “value” to be the Seller-provided estimate of value or the purchase price as the basis for the Loan Product Advisor assessment of the Mortgage. See Section 5602.3 and 5602.4 for more information on automated collateral evaluation (ACE) and ACE+ PDR, respectively. (iii) Calculation of LTV, TLTV and HTLTV ratios for Non-Loan Product Advisor Mortgages Using the “value” determined as described above, the calculation of LTV, TLTV and HTLTV for Non-Loan Product Advisor Mortgages is as follows: Calculation of LTV, TLTV and HTLTV ratios for Non-Loan Product Advisor Mortgages Ratio Calculation LTV Divide the First Lien Mortgage amount by the “value”. TLTV Divide the sum of the First Lien Mortgage amount and the disbursed amount of any secondary financing (including HELOCs) by the “value”. Calculation of LTV, TLTV and HTLTV ratios for Non-Loan Product Advisor Mortgages Ratio Calculation HTLTV Divide the sum of the First Lien Mortgage amount and the total HELOC credit line limit and any other secondary financing by the “value”. (b) Maximum LTV, TLTV and HTLTV ratios (i) Rounding requirements To determine whether a Mortgage complies with the maximum LTV, TLTV and HTLTV ratio requirements, the calculated ratio must be rounded up to the next whole number. For example, 94.01% must be rounded up to 95%. At delivery, Freddie Mac will calculate the LTV, TLTV and HTLTV ratios for each Mortgage based on data delivered by the Seller. Each ratio will be calculated to two decimal places, and the result will be rounded up to the next whole number.
