Dream -houses. [Thread] discussing my/your dream home. Or are you not a dreamer?[/thread]
So my dream House in short.
1 – Shell – Garage/Hall Like structure, yes that means no walls.
2 – Walls– However few will be painted all white.
3 – Top of the range home automation system, installed by myself which will control
Video, Audio, Heating, Lighting, Security from points all around the house, And also away from home with my Smartphone via the internet and SMS messages.
4 – Garage will be inside the house – Yes that means living with my vehicles.
5 – My Bed to be set in the center of the house – Everything same distance away from bed.
6 – Contents of the house would include, High tech Gaming PC’s, highest speed broadband, LAN capable, all new consoles out at that time, with games to boot. Epic home theater system. Bean bags would replace the traditional
sofas and chairs, fully solar /wind powered, with geothermal heating.
7 – Computer hard-drives will hold a fully functional Wikipedia to quench my thirst for knowledge in all fields for use in times of internet outages caused by the dictatorial European regime that will be in place by then.
8 – The traditional Kitchen/bathrooms randomly placed somewhere in the big open room.
9 – I will definitely be a crazy cat man, with a few bichon frise dogs(Don’t Shed),and are cute as they get.
And of course that’s not covering half the contents you’d usually find in an average house,(Art,phones,shelves (which will be cool), windows (obviously),brand of toilet paper etc etc)
I’m 18,in college studying my first year of a computer science and information technology degree. Covering programming,computer systems,electronic engineering,and energy and enviorment informatics.
Just thought that might show people where i’m coming from with all these techie ideas.
I will definitely be a crazy cat man, with a few bichon frise dogs(Don’t Shed),and are cute as they get.(cough not gay)

have been looking at some Lofts in down town salt lake city utah. I currently am making 33,600 a year. I have a 06 audi that is paid off, I don’t have a cell phone payment or health/car insurance (my parents hook that up) So my bills are basically Rent, food, gas, and entertainment. My paychecks are usually a little over a thousand every 2 weeks. The place that I am interested in was listed for 238,000 and then they just dropped the price to 198.850. My question is how low of an offer do you think i can make? My parents are giving me a down payment of 80,000 do you think that i could get it at 175,000 or 180,000? This way I will only have to borrow 100,000 and my payments will be (i think) affordable. The HOA on the building is 160 a month that includes water, internet, cable, covered parking, building insurance, and geothermal (some system where they take the earth heat to heat and cool the building so no heat or air conditioning bill)
I know they wont give me a loan i am going to do an FHA and my parents are going to co sign. I don’t have the best credit but my parents both have 800 Fi-co scores and are worth about 25 mill so I will be aproved on a loan soley becuase of them. Also last time i tried this someone was trying to say you said you make 33,600 and if you make 2 grand a month that doesnt add up please dont make stupid comments like that. I make 33,600 salary and yes i do pay my Federal taxes and State taxes so after that 2 grand a month. So what is your opinion if i have to commute to work 90 miles a day (my car gets 30mpg) , pay for gas, food, mortagage, utilities, and entertainment do you think that i can afford to have a motgauge? I hope to have a loan of about 100K so my payments will be about 800-900 a month(650 mortgage, 80 property tax,160 HOA *estimate*) . Is it possible to live as a single guy off of 1100-1200 a month paying for gas food and entertainment ect? Or am I still a little short?

I will be commuting about 90 miles a day so i will be going through alot of gas my car does get 30mpg though.

House #1 20 room mansion ( not including 8 bathrooms ) heated by natural gas. Add on a pool ( and a pool house) and a separate guest house, all heated by gas. In one month this residence consumes more energy than the average American household does in a year The average bill for electricity and natural gas runs over $2400. In natural gas alone, this property consumes more than 20 times the national average for an American home. This house is not situated in a Northern or Midwestern “snow belt” area. It’s in the South.House #2 Designed by an architecture professor at a leading national university. This house incorporates every “green” feature current home construction can provide. The house is 4,000 square feet ( 4 bedrooms ) and is nestled on a high prairie in the American southwest. A central closet in the house holds geothermal heat-pumps drawing ground water through pipes sunk 300 feet into the ground. The water (usually 67 degrees F. ) heats the house in the winter and cools it in

House #1: A 20 room mansion + 8 bathrooms, pool, pool house and guest house heated by natural gas. Monthly utilities on this house run approx $2400, more energy than most homeowners use in a year. In natural gas alone, it uses 20 times what the average American home uses.
House #2: Is a 4 bedroom house of approx 4,000 sf, nestled in the high prairie. A central closet holds geothermal heat pumps drawing water through pipes sunk 300 ft into the ground. The water (@67 degrees f) heats the house in the winter and cools it in the summer. The system uses no fossil fuels and consumes 25% of the electricity required for conventional heating/cooling. Rainwater from the roof is funnelled into a 25,000 gal cistern. Water from the sinks, baths, etc goes into underground purifying tanks and also into the cistern and is used to irrigate the land surrounding the house.
House #1 owned by Al Gore.
House #2 owned by George Bush.
Astounding.
