Financial Measures:

Potential Gross Income Multiplier (PGIM)

Also called Potential Gross Rent Multiplier(PGRM)

PGIM = Market Value or Market Value = Potential Gross Income x PGIM

Potential Gross Income

MV = EGI x EGIM

= MV

PGI

Effective gross Income Multiplier (EGIM)

Also called Effective Gross Rent Multiplier(EGRM)

EGIM = Market Value or Market Value = Effective Gross Income x EGIM

Effective Gross Income

MV = EGI x EGIM

= MV

PGI

Net Income Multiplier (NIM)

NIM = Market Value or Market Value = Net Operating Income x Net Income Multiplier

Net Operating Income

MV = NOI x NIM

= MV

NOI

Capitalization Rate (Cap Rate)

Also called Broker's Yield

Cap Rate(%) = Net Operating Income x 100 or Market Value = Operating Income x 100

Market Value Cap Rate(%)

= NOI x 100 MV = NOI x 100

MV Cap Rate(%)

Return on Equit y(ROE)

Also called: Equity Dividend Rate(EDR)

Cash on Cash Return

ROE(%) = (Net Operating Income - Debt Service) x 100

Equity

Where: Equity = Market Value - Mortgage

Debt Service = Principal & Interest Payment or MV = (NOI-DS) x 100 + Mortgage

ROE(%)

ROE(%) = Cash Flow Before Tax x 100

Equity

ROE(%) = (NOI-DS) x 100

(MV-Mtge.)

Default Ratio (Break-even) (%)

Using Potential Gross Income Using Effective Gross Income

= (Operating Expenses + Debt Service) x 100 = (Operating Expenses + Debt Service) x 100

Potential Gross Income Effective Gross Income

Financing Measures.

Debt Service Ratio (DSR) Loan to Value Ratio (%)

= Net Operating Income = Loan Amount x 100

Debt Service Market Value

Rental Apartment Building Measures.

1. Price Per Suite

2. Price Per Sq. Foot (Using Suite Areas)

3. Rents Per Sq. Foot per month

4. Operating Costs

a. Operating Costs Per Suite Per Year

b. Operating Cost per Sq. Foot per Year

5. Operating Expense Ratio (OER) = Operating Expense x 100

Effective Gross Income

Home Financing:

Gross Debt Service Ratio = (Principal + Interest + Taxes)

Gross Family Income

Lenders often modify the basic Gross Debt Service Ratio Formula.

Modified Gross Debt Service Ratio = (Principal + Interest + Taxes + Heat + % of Maintenance

Gross Family Income

Total Gross Debt Service Ratio = (Principal + Interest + Taxes + Other Debt Payments)

Gross Family Income

1. Construct an Annual Income and Expense Statement

Potential Gross Income $306,000

Less Vacancy & Bad Debt Allowance (4.5%) 13,770

Effective Gross Income $292,230

Operating Expenses 58,000

Net Operating Income $234,230

Less; Debt Service (P+i) 180,538

Cash Flow Before Tax $ 53,692

2. Calculate the Financial Measures

Potential Gross Income Multiplier (PGIM):

PGIM = MV = 3,165,000

PGI 306,000

= 10.34

Effective Gross Income Multiplier (EGIM):

EGIM = MV = 3,165,000

EGI 292,230

= 10.83

Net Income Multiplier (NIM):

NIM = MV = 3,165,000

NOI 234,230

= 13.51

Capitalization Rate (Cap Rate):

Cap Rate = NOI = 234,230 x 100

MV 3,165,000

= 7.40%

Return on Equity (ROE):

ROE = (NOI - DS) x100 = Cash Flow Before Tax x 100

EGI Equity

= 53,692 x 100

(3,165,000 - 2,056,000)

= 4.84%

Default Ratio (Breakeven):

Based on Potential Gross Income:

Default Ratio = (Operating Expenses + Debt Service) x 100

Potential Gross Income

= (58,000 + 180,538) x 100

306,000

= 77.95%

Default Ratio (Breakeven) cont.

Based on Effective Gross Income:

Default Ratio = (Operating Expenses + Debt Service) x 100

Effective Gross Income

= (58,000 + 180,538) x 100

292,230

= 81.63%

Debt Service Ratio (DSR) = Net Operating Income

Debt Service

= 234,230

180,538

= 1.30

Loan to Value Ratio % = Loan Amount x 100

Market Value

= 2,056,000 x 100

3,165,000

= 64.96%

Price Per Suite = 3,165,000

30

= $105,500

Price per Square foot = 3,165,000

24,000

= $131.88

Rent Per Sq. Foot per Mo. = 306,000

24,000 x 12

= $1.06

Operating Costs Per Suite Per Year

= 58,000

30

= $1,933

Operating Cost per Square foot per year

= 58,000

24,000

= $2.42

Operating Expense Ratio (OER)

Based on Potential Gross Income:

= Operating Expenses x 100

Potential Gross Income

= 58,000 x 100

306,000

= 18.95%

Based on Effective Gross Income:

= Operating Expenses x 100

Effective Gross Income

= 58,000 x 100

292,230

= 19.85%

Calculate the Market Value using the following financial measures

Effective Gross Income Multiplier (EGIM): 9.30

Net Income Multiplier (NIM): 12.50

Capitalization Rate (Cap Rate): 8.00%

Return on Equity (ROE): 5.57%

1. Start by constructing the Annual Income and Expense Statement

Potential Gross Income $244,800

Less Vacancy & Bad Debt Allowance (5.0%) 12,240

Effective Gross Income $232,560

Operating Expenses 49,300

Net Operating Income $183,260

Less; Debt Service (P+i) 147,500

Cash Flow Before Tax $ 35,760

2. Calculate the Market Value based on the:

Effective Gross Income Multiplier (EGIM):

MV = Effective Gross Income x EGIM

= 232,560 x 9.30

= $2,162,808

Net Income Multiplier (NIM):

MV = Net Operating x NIM

= 183,260 x 12.50

= $2,290,750

Capitalization Rate (Cap Rate):

MV = Net Operating Income x 100

Cap Rate

= 183,260 x 100

8.0

= $2,290,750

Return on Equity (ROE):

MV = (NOI - DS) x 100 + Mortgage

ROE

= (183,260 - 147,500) + 1,685,000

5.57

= $2,327,011
