My old landlord lived on less than $15k a year here in San Diego... But he owned 3 or 4 houses and lived like a hermit, he would live in whatever house wasn't rented or an extra room with his brothers. He always looked poor, acted poor and said he never had money even though he bought his F150 brand new cash after we were giving him crap for that POS Ranger he was driving, lol. We also gave him crap for an old piece of shit Yamaha Warrior 350 he was riding, while the rest of us were on 400's and Banshee's, he was chugging along in his Warrior, finally he caved and bought a brand new Suzuki 400, cash. People who make less than $15k a year in San Diego theoretically shouldn't be able to buy brand new trucks and quads cash, but they can because they were smart and invested smart before the crash.
My point is, it doesn't matter how much "income" a person makes, that's strictly for tax purposes...
And no, he didn't sell drugs, in fact he was always coming to us for his weed, best landlord I ever had. He brought an 18pk every time he'd pick up the rent
