Mastering Lot Calculations for Your Arizona Real Estate License Exam

When gearing up for your Arizona Real Estate License exam, you quickly learn that having a solid grasp of calculations and measurements can really set you apart. Let’s tackle one of the most pivotal concepts: plotting lots. Sounds simple, right? But trust me, it can get a bit tricky, especially when you throw in lots, acres, and subdivision regulations. So, let’s break it down, using a specific example; trust me, it’ll help your brain soak in all this goodness.

Imagine you’re a developer, and you’ve got 15 acres to subdivide. Your task? To figure out just how many 150 by 90-foot lots you can carve out once you factor in the space needed for streets, sidewalks, and alleys. It may feel like a lot of numbers to juggle, but stick with me; this is where your math skills shine.

Step 1: Getting to Usable Acreage

To start, we need to trim the fat from our land. If you’re reserving 20% of your land for necessary infrastructure, you’ll first need to calculate how much area this actually is. In this case, 20% of 15 acres translates to 3 acres (15 acres x 0.20). Sure, it might sting a little to set aside that much land, but it’s necessary for keeping your new neighborhood functional!

So, if you subtract that 3 acres from your 15, you’re left with 12 acres of usable land. Take a moment to appreciate that; you’ve still got a good chunk to work with!

Step 2: Converting Acres to Square Feet

Next, let’s convert these acres into square feet—because let’s be real, when it comes to real estate—or any kind of land use—square footage is where the magic happens. Each acre contains 43,560 square feet, so when you multiply 12 acres by 43,560 square feet/acre, you end up with a grand total of 522,720 square feet still ripe for development. Impressive, right?

Step 3: Figuring Out Each Lot’s Area

Now, here comes the fun part! You need to know the area of the lot you’re working with. Our lots measure 150 feet by 90 feet. So, to find the area of a single lot, it’s as simple as multiplying: 150 ft x 90 ft, which gives you 13,500 square feet per lot. It’s like finding treasure—each lot is a precious gem in your subdivided kingdom.

Step 4: Let's Calculate Those Lots!

Finally, here’s where you put it all together. Take the total square footage you calculated (522,720 sq ft) and divide it by the area of one lot (13,500 sq ft). Go ahead, pull out your calculator. When you do the math, you get about 38.7. Since you can't sell partial lots, you'll round down to 38 lots that you can actually fit on that land.

There you have it: with 15 acres and subtracting land for pathways and communal spaces, you can fit an impressive 38 lots! Pretty cool, huh? Understanding these calculations not only empowers you when you’re taking the exam, but it also sets a solid foundation for your future career.

Tips for Success on Your Exam
