Buying property in cash

[Fran Pasha]

Hello

I am new to this site but have been investing in rental property over the years. We recently sold a property and needed to reinvest. 

Me and my partner lost our jobs during Covid so loans are not possible but we own our current home where we live. Is it wise to do all cash purchase only for the rent? What else should I look at? The cash on cash ROI is only at about 2.5% considering all expenses.
