Make sure to change your air filters every 3-4 months.
Usually it would be one filter for the central heater and one for the AC intake.
While at this, clean out dryer vent annually
Also, make sure to check the lubrication on windows annually
Set aside money for repairs and upgrades
A good rule of thumb is to set aside 1% of your home’s value every year into a high yield savings account. Example - Home purchase $600,000. Make sure you save $6000 every year into an account for the unexpected.
If on the older side, it’s generally recommended to have 2% on hand in a readily accessible account
Another consideration is to simply continually adding to the fund if the home is on the much older side or has some deferred maintenance, it’s no fun replacing an AC. I personally had to install a new water heater last year
Bundle your home and auto insurance for savings
If you have multiple policies through a particular carrier, the company may simply just bundle everything and offer discounts
Maintain caulking in bathrooms, kitchens, and windows
We don't always make sure that the caulk is nice and sealed around the sink or bathtub, but it’s good to note while doing normal cleaning if it needs to be re-sealed so water doesn’t get in
Consult a tax/estate planning attorney
All homeowners may want to consult their CPA/tax professional to draft a plan for the best way to save money
Holding title and estate planning is an awfully boring thing to talk about, but is extremely important on how title is transferred and the tax consequences of it
