Why Lot Size Matters More Than Square Footage
Square footage can be renovated. Lot size and orientation are permanent. Here's why the lot size & light factor in Custom RAAM is one of the most underrated.
House hunters fixate on square footage. It shows up first in every listing description. But experienced buyers know the truth: you can add square footage to a lot; you can't add lot to a square footage.
Lot is permanent. Interior isn't. A 1,400 sq ft house on a 0.5-acre lot has options. You can add a room, expand the kitchen, build a garage. A 2,200 sq ft house on a 4,000 sq ft lot is essentially frozen. Whatever the house is today, that's roughly what it will always be—you just own more of it and pay more property tax for the privilege.
Natural light is the other half of this factor. Lot orientation determines how much sunlight enters the home. A south-facing backyard in the northern hemisphere gets sun most of the day; a north-facing lot can mean perpetual shade. This isn't a cosmetic issue—it affects heating costs, plant growth, seasonal mood, and long-term livability. Most listing descriptions don't mention lot orientation. RAAM's lot size & light factor accounts for it.
For work-from-home buyers, this factor is critical. If you're in the house 10+ hours a day, you feel the difference between a bright lot and a shaded one every single day. Many buyers who under-weighted this factor report it as their biggest regret after moving in.
For families, lot size determines outdoor life. A large lot means a yard for kids, space for a garden, room for a trampoline or a play structure. These aren't luxuries when you have children—they're daily quality-of-life factors.
How to weight it: Buyers who work from home, have children, or prioritize outdoor space should weight lot size & light at 20–30%. Buyers buying a pied-à-terre or primarily indoor lifestyle property can go lower—10–15%.
One thing to watch: Listings often advertise a lot size but don't tell you how much is usable. A lot with steep grades or wetlands is a different product than a flat, open lot of the same size. Use the RAAM factor as a starting signal, then verify with a site visit or satellite view.
The lot is the land under the dream. It's worth weighting seriously.
