Why duplexes
Two incomes, one asset
A duplex spreads vacancy risk across two leases while keeping the simplicity of a single property: one lot, one tax bill, one insurance policy and one closing. A vacancy in one unit leaves the other producing rent.
Residential financing generally covers properties of one to four units, so a duplex can often be financed on residential terms while delivering more income than a single-family rental. For investors deploying $500K to $5M, several duplexes can build a portfolio quickly without moving into commercial lending.
New construction removes the main weakness of older duplexes: deferred maintenance. Read the Houston duplex investing guide for a full walkthrough of the numbers.

For builders and developers
Duplex development, lot to buyer
Duplex product depends on the lot. Width, depth, lot size rules, deed restrictions and utility capacity decide whether two units fit and how they can be laid out. Marques sources infill lots suited to duplex and townhome construction and screens them against your product.
When the units are framed, the same network works in reverse: qualified investors on the private deal list can commit to finished or pre-sale duplexes, so a project can be sold before it is complete.
- Infill lots screened for duplex and townhome product
- Pre-sale exposure to investors who have defined their buy box
- Pricing and rent guidance from current comparable product
- One point of contact across Houston and Central Florida
