Most buyers today want a two car garage with a three bedroom, two bath home. By adding a 4th bedroom you are creating more liveable space and taking away the parking you have.
If you choose to convert a garage for any sort of use other than it's intended purpose of storage, try to make the changes minimal and easy to undo.
12 years in the business, and as a very "active" agent, I have never had a prospective Buyer get excited about a garage conversion. It may soung self-serving, and I apologize for that, but now is the time to sell and get more space...if you need it. Belmont, San Carlos, etc, very low inventory for Buyers = High Prices and Great Terms for you as a Seller. Please let me know if you wish to discuss options. 650-921-9855
Be aware that often gas fired furnaces and water heaters are in the garage and converting this space to a bedroom is not advisable.
Second, you must establish whether or not you are doing a legal or illegal conversion. A legal conversion of the garage requires permits and the city to allow the change, which might not be the case. You will have to consult a contractor and the city for that to be answered. If it is a legal conversion, you might be able to show the increase in square footage but not if it is illegal.
Third, you are taking away parking or storage. Adding a bedroom may help in one sense, but you are taking away another huge component of a home. At best it would be a wash but likely you would decrease your value.
This is a bad idea...to be honest. Spend your money on things that will give you a better return on your investment.
Swap out electrical plugs if they need to be updated and change the light switch plates if they are old and yellow.
Invest in an interior and exterior repaint.
Add recessed lights if they aren't currently there.
Invest in carpet cleaning or new carpet.
Patch leaks in the roof.
Update the landscaping and fencing to give our home great curb appeal.
Those are small items that have a huge affect on your eventual sales price. Spend your money there and you are almost guaranteed to get your investment back if not more.
Ofcourse it depends on the neighborhood but I have shown houses where the garage was converted and buyers did not want the room, they preferred a garage.
Thanks for the question!
Dallas are most families won't purchase a home unless it has a garage due to safety issues. Consider another area of home for addition than garage conversion
