I do personally think that Section 8 can be a great investment if tenants are screened properly.

That's where pricing comes in, if the property isn't priced properly, it won't get booked - and it will disappear in the rankings.3.

I wouldn’t buy a property from my mom without proper title insurance.

Houses are still selling as hot cakes with 30 days on market if priced properly and inventory that has been the same for the last 8 months (new in, old out), so be ready to be very clear on where to focus your search. 

A proper sewer inspection is critical to avoid future plumbing disasters.

(I don't give much weight to online reviews especially when most of the reviewers each have a history of only a couple of reviews.)The other guy is the estimator for a 25-year roofing company; I think they're more credible but you're probably right about them being more picky about everything.
