Pools you need determine the value of your home. You don't want to build a $50K pool if your home is only worth $150K
Pools vary in cost from $20K - $100K depends on all the adds you require, back yard, amount of construction take down a fence access to yard and etc.
In many instances with all these upgrades you like to do COULD be easier sale your or lease current property purchase one with all updates less time and expense.

Regarding the pool, $15,000 to $85,000 is the range of value on pools that my clients have added. For $15k, they got a basic playpool - unheated, with no bells and whistles. But, the pool was appropriate to the price point of the homes in the neighborhood. Anything more would have been overkill and no resale advantage. You have to be careful not to over-spend. On a $500,000 home, you can put in an $85,000 heated pool with attached spa, lighting feature, waterfall, and backyard landscaping/decking. The key with more expensive homes is keeping the pool scale in line with the scale of the house. Too small a pool with a huge house can be an objection to buyers at resale. Too large a pool, with no backyard grass whatsoever for little ones - of the human or pet nature - can be an objection, too.
Have a blessed day!
Pool....anywhere from $20000 and up....$20,000 is pretty basic and may include minimal decking and landscaping. As you go up in price of course you get more features. Maybe a heater, maybe better surfacing, more decking, waterfalls, lighting, cleaning systems, attached spa, saltwater, cabanas and the entire oasis.
Adding space to a garage on an existing house in one of the newer neighborhoods could be pretty expensive. The problem and biggest expense is engineering a slab and perhaps moving concrete back to make it happen. I'd guess starting at $20,000 if the house is built and now you want to add garage space. If building from start seems like many builders will add for $8000-$15000 1 car space depending on the neighborhood.
I'm with Lynn on this one. Why don't you search for homes with 3 car garages and an inground pool. You definitely won't get a dollar for dollar value on a pool if you go to sell the home. IE; You spend $30,000 to put in an inground pool and later decide to sell the home. In all probability, you will get $10,000-$15,000 back on appraised value. So the value placed on the pool is going to be the enjoyment you got out of it, not the dollar value in return you expect. However, if you purchase a home with one already in, then you will most likely get the same back out of it. Of course, this depends on the market trends at the time. As far as adding an addition to a garage, you need to check building codes, HOA regulations, etc.. Much easier to find one with a 3 car garage! Let me know if you need help!
I am not a general contractor but I have an idea based on my experiences. Hope that helps in some way.
