Congadulations on your home! Best advice I can give is go slow. All the DIY stuff has loads of YouTube videos to help you so just take it easy. Anything you can hook up to existing infrastructure, you can tackle easy. Installing new lighting, painting, redoing flooring, new faucets and toilets, etc.
Start top down. Roof, plumbing, foundation, grading, electrical, fixtures, cabinets, counters, paint, flooring. Water is your worst enemy, so deal with all water related problems first. Hire a licensed and bonded tradesmen for any major projects, such as roofing, electrical boxes, water heater or hvac. They will be able to work with permitting. If it’s old enough, a secondary concern will be cloth wiring, which is a fire hazard, also have your insulation checked for asbestos and your paint for lead. You’ll have to hire professionals for abatement.
These all can be done as they come up, but before any major changes are done. An example would be, if you have a boiler and radiator setup, and you want to change to central heat and air, you’ll need to have the wiring changed to handle the new load.
Thank you. I am going to do my best to remember to go slow. I’m just so excited and want to be able to get in and live here but I feel like there is a lot I want to do before moving in since it is easier.
