Well, real estate property became a good option for investment, especially after the global COVID-19 lockdown, but I suggest you buy the RV instead of buying a small cottage. Here is a high possibility that prices for the
property will fall this summer for a high value. So my advice to you is to buy a solid RV now. If prices for real estate properties don't fall, you can always buy the property, or if prices fall, you will be able to sell your RV and buy a small house cheaper.
