Unless you are a licensed plumber or electrician, you will likely have to have problems in those areas handled by a licensed professional. You may be capable of doing many of the normal carpentry things yourself, but even those should only be done with a permit and with the proper post-work inspections and approvals by your community’s local governmental body. Dong major work without permits will come back to haunt you or a future owner (who will then come looking for you anyway – and don’t for a minute think that you will be off the hook for that work).
Next, of course is to consider the cost and the return on the projects involved with the house. Here is a list of updates or home improvements, what they cost and what they normally return to the home owner.
After you have had your own conscience-cleansing meeting with yourself and determined that you are, in fact, capable, willing and can afford to take on the work (whether that be work yourself or acting in the prime contractor role for work done by professionals) involved with a true fixer-upper, then you need to look at the financing implications.
You’ll need to determine whether or not an appraisal of this jewel will come close enough to the offer price to allow you to actually finance it. Most people who take on fixer-uppers do so because they can “see the potential” in the property. Most appraisers are just looking at what is there now. There can be a big disconnect. Unfortunately there is no way to determine this short of actually having the appraisal done. Assuming that the house will appraise at a enough to let you buy it, do you have the money (or personal borrowing power) to be able to afford to do the work that is required.
