A good way to add value to your house is to do home improvement. Many renovation and home additions add value to the house. Also, painting by interior painting San Jose is a good way to add value to the house. One of the simplest and most cost-effective improvement is house painting. Low-maintenance landscaping also adds value when you sell your house.

Adding the stylish furniture in home can be very effective in increasing the home vlaue. 

You might want to look into AB2299 for the state of California. Add additional living area and raise the value 160k-400K to all R1 Properties. We build these for a living and are seeing a 2% return rate on your investment.

Same as others said, Remodeling magazine's Cost Vs. Value report is a great resource!

As a roofing contractor, of course I am going to suggest an upgrade to your roofing system. And that's not just a biased opinion either. Working with a lot of realtors in our area it has been proven that the roof can be as much as 40% of your curb appeal. Especially when the system incudes things like the right color drip edge on the rakes and eaves, and high profile ridge caps. Both of those items are relatively inexpensive and can make a very noticibale difference compared to homes that don't have them. Selecting the proper type of shingle of course also plays a huge role. About 95% of re-roofs these days use a standard architectural tpye compositions shingle but picking something from the designer line can realy make your home stand apart. Then again, other rof covering options besides ashphalt shingles can make an even greater impact. 

As a GAF Master Elite Copntractor, we are partial to their line of products and I have included a link below to their designer apshpalt series.

Good luck!

I agree with Chris.  The Cost vs Value report is the "go to" guide and is impartial.  Personally, I like to focus on first impressions and curb appeal.  Exterior dressings like corwn mouldings and simple shrub pruning is a great low cost way to give the home a wow factor.

You might also contact a couple of local realtors to see what people in your area are looking for in the home they want to purchase.

Check out the 2018 Cost vs Value Report from Remodeling Magazine.

2018 Remodeling Cost vs Value Report

This will give you an idea of the average return on your investment in the region where you live.

The one factor it will not give you is number of intangibles you may receive from the project you're considering.

• Lifestyle enhancement
• Number of years living in your new space
• New opportunities the space now provides

Make sure those are also part of your equation before making a final decision on the impact a remodeling project may make on the "value" of your home.

I would recommend that you look at remodeling magazine. They do an annual study of cost versus value For mini interior and exterior home improvements.
