Finding an experienced RELIABLE business savvy contractor in the housing market that you are working is harder than ever nowadays, imo. 

Nowadays craigslist is so full of spam from large apartment complexes and scams that tenants interested in SFRs struggle to find something legitimate.  

That is all I do nowadays.

The next door neighbor has subdivided his house for rental, erected 2 rental units in the back yard and put in additional parking on his property.

Nowadays, I only invest in 1sts.

The first three that come to mind (but are most definitely not the only ones) are:1) Cashflow: - Getting cash-flowing properties nowadays is a bit more difficult because of how the rents seem to have flattened and the interest rates that increase your monthly PITI payment being where they are.

Anyway, the class had a formula to make anyone $120K in 90 days...without giving the whole breakdown, I'll just say the beginning is to do 5 wholesale deals,well I tried craigslist to search for motivated sellers and cash buyers (which i think everyone is going on nowadays), listsource.com to see where the hottest area's cash buyers are buying, and listsource.com to get names of motivated sellers so I can upload my list into websites such as, "Click 2 Mail" or "Go Big Yellow Letter" for my direct mail but the problem is...with the criteria I entered for listsource, my mailing list was only 5 names for the sellers list/ 502 for potential cash buyer lists (good but I need deals first) , craigslist is now too competitive (it seems).

Most wouldn't find their way to a specific book nowadays without getting funneled in from another source is my suspicion. 

Nowadays most states do a voucher program for section 8, which pays the tenants rent.

@Karen Grethlein Allegheny is starting to get saturated because of the amount of out of state investment going on here nowadays.
