HGTV said it has greenlighted four new shows in the theme of buying "the worst home on the best block" and then restoring and potentially re-selling it, a theme that has been successful at the Scripps Networks outlet (see " 'Flip Or Flop' Notches Series High"). They are likely to make their debut this summer, the network said, with scheduling yet to be determined.

In Flipping Virgins (a working title), property expert Egypt Sherrod (pictured) advises first-time flippers the ultimate tutorial in the risky world of flipping houses.

Old Home Love (w.t.) showcases Utah couple Andy and Candis Meredith as they renovate dilapidated houses from the 1800s and restore them to their original beauty.

Shalina Joy, a New Jersey teacher and single mom of two, takes on her biggest summer vacation project ever: transforming a run-down 1900s mansion into a sunny, functional home for her family in Restoring Victoria, also a working title.

And Flipping Moms gives popular authors and mom bloggers Jen Pate and Barb Machen center stage as they try to balance busy family lives with buying, renovating and selling fixer uppers. 

“Viewers are very interested in renovation and flipping when it leads to the outcome that every community wants -- restored, well-maintained homes,” Allison Page, general manager, HGTV and DIY Network, said in a release. “HGTV has had tremendous success with series like Rehab Addict and Fixer Upper which showcase real people who have a passion for renovating older properties to enhance their value to the overall community.”

HGTV had a solid 2014, a down year for most cable programmers, with primetime ratings growing 4%. Top viewed series were Property Brothers, Property Brothers at Home, Flipping the Block and Tiny House Hunters, per the network.

HGTV said its Sunday (July 20) premiere of new renovation-competition series Flipping The Block (pictured) was one of the best ever at the network, averaging 1.6 million viewers during its 9 p.m. time slot, part of the highest-ever rated Sunday for the Scripps Networks outlet.

Flipping the Block, produced by Authentic Entertainment and featuring HGTV and DIY Network's Josh Temple (House Crashers), Nicole Curtis (Rehab Addict) and Scott McGillivray (Income Property), also drew a 0.81 rating among viewers ages 25-54. Beachfront Bargain Hunt, with two episodes starting at 8 p.m., garnered a 0.92 rating in the 25-54 bracket, "a 'best-ever performance' for the series and a 61% increase over recent levels," HGTV said. The first episode averaged 1.9 million viewers and the second averaged 2.1 million, the network said. 

Overall, HGTV averaged a 0.73 primetime rating among viewers ages 25-54 and delivered its highest Sunday primetime rating since March 2011, the network said. On a total day basis, the network said it attracted more than 15 million viewers.  

"To launch a brand new primetime series on the most competitive night of the week and have it propel HGTV to the No. 1 spot among women and the highest rated Sunday ever in total day is exactly the kind of performance that our sponsors and partners want to see," Kathleen Finch, president, HGTV and DIY Network, said in a release. "We know what's at stake and have worked toward this outcome for months. Top 10 never gets tired." 

HGTV also said the 7:30 p.m. episode of Flip or Flop had a 1.07 rating among viewers ages 25-54. Nielsen live-plus-same-day figures report 2.035 million viewers on average for that episode.
