Wanting to make a new investment

$100K probably won’t buy any property that could be turned into a rental. However, you might be able to use that as a down payment.
I suggest you look in the vicinity of your main rental so it’s easy to add on to the management of your first property. Keeping your incremental costs low for the second property is a significant factor in getting a good return. For instance, using the same type/color of towels in both properties means you don’t have to keep many spares on hand.
And since you already know the local market, you can put together a reasonable business plan for when you apply for a mortgage.
