課程六 : Real Estate Financing

Flow of Real Estate Financial Capital

• The issues:• Real estate is capital intensive

• Typical capital structure is dominated by debt

• That is a major portion of the funds to purchase a home or construct an office building, etc must be borrowed

• The segment of the capital markets where these funds come from are called mortgage markets

• This sector of the debt market is by far the largest in the US and in some respect the world

Flow of Real Estate Financial Capital

• Potential developers, homeowners etc. must obtain financing in order to build, own and operate properties

• Funds are supplied by a variety of individuals, firms, institutions and government as shown in the figure

• Between the users and the sources of funds are a number of service organizations that make the raising of capital easier and more efficient

• Financial capital flows from suppliers to users in the form of debt (mortgage) and equity

• Providers of debt have priority claim on the revenue from operation• Equity holders have residual claim on cash flow

Why Study Mortgage Market ?

• Shed light on how traditional method of financing assets by financial intermediaries is rapidly changing

• securitization is the new BIG BROTHER

• Demonstrates how financial engineering can redirect cash flows to create securities that more closely satisfy the asset/liability needs of investors

• Government agencies provide Credit guarantees for mortgage backed securities

• should government agencies continue to provide guarantee

Supply of loanable funds

• The amount of funds borrowed and lent depends on interest rates.– As rates rise many spending units save more and spend less

– Simultaneously when interest rates rise many spending units demand less credit

– The figure following illustrates the operation of supply and demand for loanable funds

– The demand schedule is downward sloping, reflecting greater willingness to borrow at lower rates.

– The supply schedule, s1, rise to the right, because people have more to lend at higher rates

– The intersection of the of the two schedules determines the amount of funds lent, f1, and the prevailing interest rate, i1

Real Estate Financial Instrument

• When ever real estate is financed, the property is pledged as collateral or security creating a financial instrument known either as MORTGAGE or DEED OF TRUST Power of secured debt: attempting to buy a $300 suit on credit versus obtaining $200,000 loan to build a house

– Mortgage : Two Parties– Deed of Trust : Three Parties– Promissory Note– Title Pledge

Risks faced by mortgage finance intermediaries

• Credit risk:

• risk that money borrowed might not returned timely

• Default risk:

• risk that money lent might not be repaid

• Cash flow risk:

• risk that market conditions will alter scheduled cash flows

– prepayment risk

– inflation risk

– exchange risk

– interest rate risk

• Liquidity risk:

• risk that money will be needed before it is due

Mortgage Contract Rate

Generalized Mortgage Contract Rate

Rj = R* + (1-a)D + a E(P)

where:

Rj = contract interest rate on mortgage of type j.

R* = real rate of return

a = risk sharing parameter

D = risk loading

P = pure interest rate risk component

j = term of loan

a = 1

Rj = R* + E(P) Uncapped ARM or free floating rate.

0 < a < 1

Rj = R* + (1-a)D + aE(P) Capped ARM

a = 0

Rj = R* + D FRM

Contact rate = risk free rate + liquidity + default + prepayment + inflation + interest rate risk + origination and servicing cost

Mortgage Contract Rate

Mathematics of level-payment mortgages

• Mortgage investors must be able to calculate scheduled cash flows associated with mortgages.

• Servicers of mortgages must be able to calculate servicing fee

• We also need to know cash flow from mortgage pools to price MBS

Monthly Mortgage Payment• Mortgage payment requires the application of PVA

• PVA = A[1-(1+i)-n]/i– where:– A = amount of annuity– n = number of periods– PVA = present value of annuity – i = periodic interest rate

• The term in the outer bracket is called the present value of annuity factor (PVAF)

• Redefine terms for level pay mortgage

• MB0 = DS([1-(1+i)-n]/i)

– where:– DS = monthly mortgage payment– n = amortization period or term or mortgage

– MB0 = original mortgage amount

– i = simple monthly interest (annual/12)• Solving for DS gives

• DS = MB0{[i(1+i)n]/[(1+i)n -1 )]}

• The term in outer bracket is called mortgage constant or payment factor

• So what is a mortgage constant (MC)?

Illustration

• Original mortgage balance (MB0) = $100,000, term/amortization period (n) = 360 mons., interest rate (i) = 9.5 or .095/12 = .0079167

• DS = MB0{[i(1+i)n]/[(1+i)n -1 )]}• DS = $1,000,000{[.0079167(1.007967)360]/[(1.0079167)360 - 1]}

• = $100,000(.0084085) = $840.85

• Illustration using calculator:

-$100,000 = PV ; 9.5/12 = I; 30x12 = n; PMT = ?

Mortgage Balance• Mortgage Balance each period is given by the ff. formula

• MBt = MB0{[(1+i)n - (1+i)t]/[(1+i)n - 1]},

• where MB0 = mortgage balance after t months

• Example: Mortgage balance in 210th month is

• t = 210; n = 360; MB0 = $100,000; i = .095/12 = .0079167

• MB210 = 100,000{[(1.0079167)360 - (1.0079167)210]/[(1.0079167)360 - 1]} = $73,668

• Check (calculator): $840.85 = PMT 9.5/12 = i ; 150 = n PV =? $73,668

• Scheduled principal payment (Pt) is

• Pt = MB0{[i(1+i)t-1]/[(1+i)n - 1]

• Example: Scheduled principal payment for 210th month is

• P210 = {[.0079167(1.0079167)210 - 1]/[(1.0079167)360-1]}

• = 100,000{.0079167(5.19696) = $255.62

• CHECK:

• 840.85 = PMT ; 9.5/12 = i ; 13x12 = n ; PV = $75,171.72

• Balance at end of month 210 = $73,667.78

• Scheduled principal paid = $75,171.72 - $73,667.78 = $1503.94

Scheduled Principal Payment

Scheduled Interest• Scheduled interest is as follows:

• It = MB0{i[(1+i)n - (1+i)t-1]/[(1+i)n - 1]}

• where It = interest in month t

• Example: scheduled interest in month t is • I210 = 100,000{.0079167[(1.0079167)360 - (1.0079167)210 - 1]/

[(1.0079167)360 - 1]}

• = 100,000{.0079167[(17.095 - 5.19696)]/[17.095 - 1]} = $585.23

• CHECK

• Debt Service = 255. 62(p) + 585.23 (i) = $840.85

Monthly Mortgage Cash flow• If the mortgage investor services the mortgage the investor’s cash flo

w is principal, interest payment

• If the investor sells the right to service the mortgage the interest income is net of servicing fee

• Servicing fee = [MBt(servicing fee rate)]/12

• Example: assume servicing fee rate is .5%, then servicing fee for month 211 is = [(73,668)(.005)]/12 = 368.34/12 = $30.70

• Note the balance at end of month 210 ($73,668)is the beginning balance for month 211

• Net interest payment for month 211 = $583.21 - 30.70 = $552.51

Mortgage Amortization Schedule

Interest Rate = 10%

Term of Loan or amortization period = 30 yrs.

Mortgage Constant = .10608

Yearly payment

Debt Service = Loan Amount x Mortgage Constant

= 100,000 x .10608

Yearly Payment = $10,608

Alternatives For Determining Mortgage Balance

1. Present value of annuity factor (PVAF)

PVAF i%, n - t

Proportion Outstanding = ---------------------------

PVAF i%, n

where

n = the period over which the loan is amortized

t = period in which balance is desired

n - t = remaining life of the loan

Alternative method of determining mortgage balance

2. Mortgage Constant (MC)

MC i%, n

Proportion Outstanding = ---------------------------

MC i%, n - t

Example

What is the proportion outstanding at the end of 10th year for a loan which is fully amortizing, with a term of 30 years, interest rate of 10%, monthly payments. The original loan amount is $100,000

PVAF 10/12%, 240 mon. 103.624619

PO = ------------------------------- = --------------- = .909380195

PVAF 10/12%, 360 mon 113.950820

Therefore balance outstanding = (.909380195)(100,000) = $90,938.02

Example

Mortgage Constant Approach

MC 10/12%, 360 mon .008776

PO = -------------------------- = ------------- = .909430051

MC 10/12%, 240 mon .009650

Proportion paid off = (1 - .909430051) = .0905699

Outstanding loan amount = 100,000x.909430051 = $90,943.0051

Alternatives for Determining %of Loan Outstanding

3. Future value of annuity factor (FVAF):

FVAF t , i

PO = 1 - ------------------------

FVAFn, i

204.844979

= 1 - --------------------- = .909380194

2260.487925

where:

FVAFt = future value of annuity factor in period t

FVAFn = future value of annuity factor in period n

t = year in which balance is desired

n = term or amortization period of loan
