The bank remodel most of the house put in new windows a new roof and refurbish all the original hardwood floors.

@Andrew George Dennis so are you asking because you have a specific project or because you want to figure the costs for a remodel?

I'm having a hard time with the construction cost estimate portion of the calculators though, as I have no idea how much it costs to remodel things.

Hey you guys I’m in the Dallas Tx area and My realtor sent me a property valued at 90K on MLS, I checked for the surrounding area and all the properties around a valued at 140k+ , the house will need definite remodel inside to make it more appealing for a potential rental or even a flip.

I'd like to hear more about what type of property and how extensive a remodel you are planning on doing on each property.

And putting all the money together and remodeled the lot and adding another bedroom and garage and sell the property triple to make profits?

I do have some experience in remodeling so fixing and flipping is also attractive to me.

We have remodeled a variety of other properties and done some flips as well.Our current lifestyle leaves us more available than ever to throw ourselves into opportunities.
