Jim thank you very much for your answer. I’m gonna go with a rough estimate from a contractor I know.

Question about adding 2 rooms - Posted by Fern (CA)

I’m in the process of possibly obtaining a house for $115,000. It is only a 1bd 1ba 800 sqft home but it is on a nice 7,500 sqft lot. The home itself as it is needs about $1000 in repairs. But I would like to add two rooms and possibly a bathroom. The thing is that I can’t get any contractors to go give a bid yet because the owner is still living there. I’m a realtor and I have an appointment with the owner for a possible listing. But if the deal is sweet enough i will offer to buy it myself without commissions involved. I just need a rough idea on cost to add 2 12’ x 12’ rooms. The ARV is eaisly $160000 in that area. And I mean that If I listed a “new” 3bd 1ba int hat area for $160,000 I would have it sold in less than 7 days for sure. SO I would put an add in the penny saver which generates hundreds of calls on deals that aren’t even this sweet and hope to double end it. and the most I can sell it for is $180,000. So again my main question is if any body can give me a rough figure on adding two rooms to a house.

Why can’t you get a contractor to look at it? Make a written offer conditional on inspection by your contractor. Then get a firm quote. If it is too high you may have to renegotiate but in any case you can back out if the contractor’s report is not satisfactory.

It’s really tough to give an intelligent answer because I am not clear if is an addition to the side of the house, a second floor addition, finishing off interior space etc. Also, I have found that estimates I get on residential work tends to vary a lot more than on commercial projects (percentage wise). furthermore, construction costs vary depending on region and the amount of construction activity there is in a particular area at a given time. All of that said, I normally figure somewhere around a $125 bucks a Sq ft for additions. Up here construction activity is down and so are the prices.

You are looking at building (2) 12’ x 12’ spaces that would be 288 total sq. ft. 288 x $125 totals around $36,000.

With all of that said, if your contractor is very well experienced he could give you a BUDGET number (based on sq footage & construction type) you can use without him ever looking at the place. I do a lot of design/build work and the contractors I use ALWAYS provide initial budget numbers before I design a thing. I recommend that you not rely on my numbers and get your contractor to provide you a budget number.

Good luck
