Home Addition vs. Buying a Bigger House — What Makes Sense in Orlando?

March 2026 · 6 min read · Karhan Construction & Remodeling

You've outgrown your home. Maybe a new baby, aging parents moving in, or you're finally ready for that home office and guest room. The question facing a lot of Orlando homeowners right now: do you add on to what you have, or sell and buy something bigger?

Adding space means structural work — reframing during one of our Orlando-area projects.

With Orlando home prices elevated and interest rates still high, this decision deserves careful thought. Here's how we'd think through it.

The Case for a Home Addition

You keep your mortgage rate

If you bought your home before 2022, you likely have a rate between 2.5–4%. Selling means giving that up and financing a new home at 6–7%+. On a $400,000 mortgage, that's roughly $800–$1,000/month more in interest alone. A home addition financed with a HELOC or home equity loan is almost always cheaper than a new mortgage at today's rates.

You stay in your neighborhood

School district, neighbors, commute, community — you already like where you live. Moving disrupts all of that.

You get exactly what you want

A home addition is designed around your specific needs. You're not compromising on someone else's floor plan.

Cost range for additions in Orlando

  • Basic room addition (400 sq ft): $60,000–$100,000
  • In-law suite with bath and kitchenette: $80,000–$150,000
  • Second story addition: $150,000–$300,000+

The Case for Buying a Bigger House

Your lot can't support an addition

HOA restrictions, setback requirements, or simply not having the yard space can make a meaningful addition impossible. We'll tell you upfront if your property has constraints.

Your home needs too much work overall

If your home is aging and needs a new roof, HVAC, and electrical on top of more space, moving might be the smarter financial play.

You want a dramatically different location

Closer to work, better schools, different neighborhood — an addition can't solve a location problem.

The Real Math for Orlando Homeowners

Let's say you need 500 more square feet. Adding on might cost $80,000–$120,000. Selling your home, buying costs (realtor fees, closing costs, moving) typically run 8–10% of your home's value — on a $450,000 home, that's $36,000–$45,000 just in transaction costs, before the new mortgage premium.

For most Orlando homeowners with a sub-4% mortgage, adding on is the financially smarter move — often by a wide margin.

What About Resale Value?

A well-executed room addition in Orlando returns 50–65% of its cost in resale value — less than a kitchen or bathroom, but you're also gaining livable space that makes your home more enjoyable right now.
