In her newest Instagram post, Joanna writes: "We are now opening another vacation rental! Chip and I had so much fun restoring this old Waco icon and cannot wait to welcome guests starting this fall. The house dates back to 1903 and we definitely kept its old world charm..."

She added: "Our hope is that friends and families from all over can make lasting memories here during their visit to Waco."

As you’d imagine, the 7 bedroom, 3.5 bath home is gorgeous and has been completely remodeled with all of Joanna's signature interior design charm. The home sleeps 12.

They also have The Magnolia House rental, which has booked solid within minutes when reservations were made available.
