If you'd like to receive top dollar, then you'd better be prepared to pay some professionals to do the work--unless you're a licensed carpenter or contractor. Many sellers think that they can take a few cheaper short-cuts here and there, and that the buyers won't notice. Whether or not the buyers will notice the flaws/short-cuts, their inspectors usually will notice the flaws/short-cuts and flag them (if they're good). The net result is that the seller will end up paying the full price--if not more--for the work anyway (typically via a credit).
So if you'd prefer to save money, then sell it as-is.
In today's home selling climate, buyers are very picky. I find that repair requests going back to sellers after inspections are much longer lists than in previous years. By making the repairs now, you can schedule the work at your convenience and have the time to get several bids on a repair so that you aren't paying top dollar. Buyers aren't going to pretend that something doesn't need repair -- even if you lower the price to "compensate" for an "as is" condition. They'll still want it fixed. The other thing to remember is that as a home owner you know that certain things can be repaired. Buyers want broken things replaced with new ones -- given the choice that's what they'll ask for -- and they will ask for a professionally licensed contractor to do the work -- not you or your perfectly competent :"Uncle Fred".
Since you have an older home to which the previous homeowner made additions, it's probably worth the money to have the home pre-inspected to find out what the buyer's inspector is going to flag. It will cost you about $350 but it will give you a marketing tool when you sell the house. A copy of the inspection report and a list of the repairs made will make buyers feel more comfortable about purchasing the house. Also consider offering a home warranty with the purchase.

Yes it would be wise to take care of any issues with your home, before you list it for sale. If you don't the buyer will likely reduce their offer, or ask you to repair them anyway. When a home is in good condition, you will get better buyesr and higher offers too.
