## Math is Everywhere

Apartment properties are valued based on their income, and your financials are the “mirror” that reflects the health and strength of that income.

### Daily Division

A 650 square foot apartment rents for $725. What is its rent per square foot?

A marketing company agrees to change your ad no less than 17 times in a year. How many times will the ad be changed each month?

Each week for the last 12 weeks you have had to replace 14 toilet flappers. How many flappers have you replaced? If each costs $2.42, how much have you spent in total?

### Percentages

To find what percent one number is of another, divide the PART by the WHOLE.

Example: 7 is what percent of 48?

### Percentage Portions

Vacancy Loss this month is $2,486. Gross Potential Rent is $126,106. What is the percent of vacancy loss?

A property has 294 units. 124 are one bedrooms– what percent of the property is TWO bedrooms?

### Decimal & Percent Problems

Annual Gross Potential Rent is $826,106. Collections Losses are 1.4% of GPR. How much are Collections Losses?

## Budgets, Variances, Trends and the Owner’s Point of View

### Variances

A variance is an amount that varies from a projected amount. It can be a favorable variance or an unfavorable variance. It may be expressed as a variance percentage, a variance dollar or % of GPR.

### Sample Variance

EXAMPLE: Other Income is budgeted for the year at $172,500. Actual Other income for the year is $164,859. What is the variance to budget?

172,500 – 164,859 = (7,641) negative variance. 7,641divided by $172,500 (budget) = .0442956 or (4.4%) variance to budget.
