Another option for the rental property is to 1031 exchange it as well.

The seller wants to close by June 10th so he can 1031 exchange.  

DSTs are an advanced version of statutory trust that allows investors to transfer 1031 exchange money into.

I will be standing outside a property and some random guy will drive up and ask if I am selling, and we'll wind up talking about real estate for an hour and exchange numbers... but send a virtual assistant to call me 3x per week and not even reveal the name of the company she works for and you will get "smug" posts complaining about it..... and I only complain, I've never turned anyone in (yet) or really interfered with anyone's business. 

The 1031 exchange can be used to go into any other type or size of investment real estate, including some fractional passive instruments like Delaware Statutory Trusts and Tenants in Common properties. 

You could also 1031 exchange one or more of the paid off properties into something bigger as others have recommended.

I see the best plays right now in countries with currency plays (Brazil) and/or heavily dependent on tourism which has been crushed  by Covid (Italy).  

I just sold a property and am executing a 1031 exchange.

Make sure your management company also gets a release of all claims by the tenant in exchange for the money. 

Do you have any advice on researching currency or how to mitigate that risk most effectively?
