Owning an apartment complex is a great investment. While there are associated costs with building one, such as building size and location, the cost of owning the complex should only be 20- 50% of the income it generates. When managed properly, it can become a great asset that can bring thousands of dollars every month for the owner.

Because of this, more developers and business owners are building and purchasing apartment complexes. With this, there will be an increase in the demand for apartment complex blueprints and for general contractors that will have to estimate the costs. 

If you’re a project owner, general contractor, or a seasoned estimator looking for apartment complex floor plans, then this guide is for you. We have reviewed multiple apartment complex plans along with a specific AI estimating software that can help you estimate their costs. Leverage them to streamline your next apartment complex project.

Streamline the Cost Estimation of Apartment Complex Blueprints With Togal.AI

While there are a couple of associated costs when owning an apartment complex, it’s still a great investment. The multi-family housing market is strong and real estate investments inevitably increase in value over time. With revenue coming in from rent every month, it’s an excellent source of cash flow that can protect against inflation in two ways - through capital appreciation and rent increases. 

Thus, more homeowners, investors, and developers are building and buying apartment complexes, resulting in more apartment complex construction projects for general contractors. Typically, the cost to build an apartment complex can be as small as $1.1 million or as high as $160.5 million. There are just too many factors to consider, including the type of building, number of floors, materials used, inflation, number of units, permits, location, and design. 

For faster and more accurate takeoffs and cost estimation for your apartment complex projects, leverage our AI estimating software, Togal.AI. With Togal.AI, you can finish takeoffs in seconds with 97% accuracy.
