We have a second home in a coastal village which we use every weekend. We are at home mon - thurs. and spend fri - sun at our second home. It works well for us. It is a luxury but one we have worked hard for.
So for this example, if this couple (I'm assuming no kids as they say they are doing Fri-Sun) are genuinely spending every weekend of the year at their second home. Presumably some holiday in other places but also some holiday time more than the weekend there too.
They are spending 208 days in their first home and 156 in their second home.
So they've got a rough 60/40 percentage split between the two homes.
Positives:
If it's year-round then they are not leaving a house just empty and dark for months on end.
They are spending 40 percent of their life there so presuming they are not buying all their food, household stuff, hardware, petrol etc in home 1 area and importing it they are supporting some local services and showing a need for them.
It's a significant enough time to be able to make a real effort to support local community events.
Negatives:
It's only the weekends so probably not using much public transport or not using the types of public transport that local people need to get around for work
Probably not registered to a GP there
Probably not using local post office much
Not using schools and other kid-related services (although if their 'spot' was replaced with a permanent resident without kids, that's the same.
@ultrababy How interested are you in the community you have your second home in? Do you read the local papers and care about the issues affecting residents who live there full-time?
Would you notice a campaign to save a bus route? Or fix a local playground to make it safer? Or are you more in holiday mode when you are in your second home?
