Own Single Family Home. Do I downsize to a condo?

[Logan Rex]

I currently own a 3b,2.5b single family home. 1800 sq ft. I am currently in the market of buying something else, thinking about downsizing to a condo. I would then rent out my SFH. BUT, I just want to know if I downsize and buy a luxury condo, is that a good investment? Of course my relator says yes but others I've talked to said to get a townhome instead. I do plan on living in the condo for at least a year or 2 then trying to move and buy another property. Advice please!
