software to design before start house development/ rehab

[Jay P.]

I've seen quite before and after pictures of the houses that real estate investors put on their blogposts. 
I believe that the kind of colors they use for interior and exterior of the house makes a huge difference in the amount of profit that the house would generate. After watching the TV shows on flipping on netflix where they transfer 2bd house to 3 bd to increase its price, or create an attached bathroom for a master bedroom and different kinds of techniques they'll (usually the females) use make the place look spacious & beautiful.    And quite honestly they work!                                      My question is how often does a typical real estate investor use some kind of software like photoshop or other fancy softwares to really visualize the change before they start working on it ?
