Understanding your top priorities can help in determining whether Stessa, Baselane, or another tool might best fit your needs.If you're comfortable with apartments.co for rent collection but want higher yields on your cash (this is me reading between the lines) you could have the transfers go into a high yield business account like BlueVine 1.5% interest or something like CapitalOne 3.9%.
