There isn't a definitive answer to this question. You should look at each home for its individual characteristics. Generally, older homes may be in more established neighborhoods, offer more ambiance, and have lower property tax rates. People who buy older homes, however, shouldn't mind maintaining their home and making some repairs. Newer homes tend to use more modern architecture and systems, are usually easier to maintain, and may be more energy-efficient. People who buy new homes often don't want to worry initially about upkeep and repairs.
One of the most important things to be aware of is that paint is formulated for either interior use or exterior use, and they have different properties: Interior paint is formulated for: Scrubbability and stain resistance; Good hiding ability; Splatter resistance; Easy touch-up. Exterior paint is formulated for: Color retention; Resistance to fading; Flexibility to withstand expansion and contraction due to weather; To provide a mildew resistant coating; Resistance to tannin bleed. Don’t think that you should use exterior paints indoors on the assumption that it is “tougher”. In fact, some of the highest-grade exterior paints can be worse to use indoors than a lower-quality interior paint.
