💵What this unit actually costs per month

$6,939/mo all-in
20% down at 7.18% (this week's 30-year average) · mortgage + tax + insurance + HOA
Mortgage principal & interest$4,660
Property tax (1.30% effective)$932
Insurance (estimate)$50
HOA dues$1,297
Total monthly$6,939
Rough cash to close$193,478

Financing type

Not FHA-approved. No 3.5%-down FHA financing on this unit, so the realistic floor is a 5%-down conventional loan ($42,995). Common for small associations and not a defect on its own, but it does remove FHA buyers from your resale pool.

Rate is the Freddie Mac PMMS 30-year average for the week of 2026-11-05 — a national survey figure, not a quote. Tax, insurance and closing costs are estimates; your own Loan Estimate is the real number.

Description

Former model home, fully upgraded, and it shows. This corner residence at MIRA gets light from two directions thanks to an extra line of glass, so the space feels bigger and brighter than the floor plan suggests.

The amenities make it easy to entertain without hosting at home. The owners' clubhouse flows from indoors to outdoors, with a formal dining room, a full kitchen, wine fridges, and an oversized island with seating and AV.
