When deciding on Product for Painting interior rooms of Foreclosures, pick neutral colors, work with water based latex products wherever possible for easy application and cleanup. Use Semi-Gloss product in all kitchens, bathrooms and other high traffic areas. Use Flat Latex in Living rooms, Bedrooms, and other low traffic areas and you might include ceilings in all the rooms with this category. Use drop cloths and here too, don't cheap out, get ones that are effective and will last.
Before painting, slosh your brush in whatever solvent you will be using at the end of the day to clean the brush (i.e., water for latex, mineral spirits for oil, etc.) It'll be easier to clean when you're done
2. Wrap your Brush or Roller
If you don't feel like cleaning your brush or roller at the end of the day and expect to get back to painting within a few days, wrap the brush or roller tight in a plastic bag and put in the freezer.
3. Latex Gloves or Lotion, your Pick
Latex gloves are great for keeping your hands clean (especially if you're using oil-based product!). If you can't stand latex gloves or are allergic, a thick application of hand lotion before beginning will make cleaning a lot easier later on.
4. Wet Edge
Always keep a wet edge as you work, and work away from that wet edge. If you finish over a dry edge, you will get overlap marks.
5. Avoid Cheap Roller Covers and Brushes
This one is important. Cheap roller covers leave fuzz on the wall. Cheap brushes leave streaky brush marks. Avoid those multi-packs of rollers, ten for a dollar. Pay the extra few cents and get better tools. It'll be worth it. Honest it will. If you get the cheap rollers they will be good for a room or two and then they are shot. I bought 3 rollers, expensive ones with ball bearings and I still have 2 of them 14 years later!
Also buy a quality extension for your roller, invaluable when finishing walls and ceilings. This saves your wrists, hands, etc., from undue discomfort after a few hours of work.
6. Test for Loose Paint
Will the existing finished or primed surface take new material? And hold it for years to come? Test this out by adhering a strip of duct tape to the existing surface and.. ripping it away. If flakes of material more than microscopic size come off, you may need to scrape and sand.
7. Low-Stick Masking Tape
Also known as "blue tape," this tape comes off easier and doesn't peel off primer or existing finish. Blue tape, by itself, will save you at least an hour of frustration over the old-style beige masking tape.
8. Rein in Your Paint Can Opener
Can openers, those little metal keys (you do use one, don't you?) are notorious for getting lost in the shuffle. Chain It to a small chunk of wood just like a public bathroom key. Whatever you do, just don't lose It!
