Wayne market? 

You need income to qualify for loans, you can learn how to manage rentals well (something most landlords never do), you will figure out which communities/properties make the best investments, can earn an above-average paycheck, and may even find some investment properties before they hit the market.

Or find a deal first then market it to buyers, then offer on the house and create an agreement with the seller & buyer?

There aren't any good wholesalers in the Cleveland market.

But, the self-sufficiency test for FHA loans can be really difficult in SF, meaning that the market rent from units you will not occupy must be sufficient to pay for the mortgage payment. 

@Joe Frank I’m a huge fan of Turbo Tenant to market properties, manage leads, screen tenants and lease up.

In a highly competitive tourist market like New Orleans, I update my photos weekly. 

It requires no money upfront, so you will join thousands of others trying to do the same in your market.

I use Facebook marketplace as my way of marketing my rentals.

To find value on residential 1-4 unit properties you could ask your realtor to run comps or complete a CMA(Comparative Market Analysis) on a subject property once you find it.or you can find the value on your own.We use prop stream to run comps.
