There are many ways to get to the beach, and this is my perspective. Likewise, there are many ways to have a 1st or 2nd home on the beach. We have had a house on the beach for most of the last 20 years, and they were 2nd houses. The first one more than doubled in price after a hurricane made it one of the few spots that was available.
Many can afford to have a house that only they stay in, but that is not the only option. An inexpensive condo that is 120K can gross over 16,000 a year and net after taxes, utilities, and repair around 10,000. From people I have talked to, it is normally about 6-8% on a condo that was purchased at the right price. This kind of return is not a bad way to invest for the future, because condos are in short supply and will usually accrue or go up in value. We had one that went up 3 times the amount we gave for it. I will say you may have to wait, but it is possible.
If you have enough emergency fund in reserve to try a condo for rental, be sure and check out VRBO and other sites for rental opportunities. Also, it is good to have a trusted local person to do cleaning for you that will keep an eye on your condo. The outlook is pretty good for rentals and property investment.
If you do not agree, maybe the stock market is a better place for you.
