We have been doing Rehabs for a couple of years and our marketing occasionally yields a property that we can buy at a discount but doesn't fit the full Rehab model.

Is there any tips on how to find off-market houses that I can buy at a discounted price?

Banks and credit unions can also offer flexibility for investors that engage in strong relationship-building strategies, offering discounts and solid loans in exchange for borrowers willing to use the institution for other purposes (savings accounts, etc.).

Realtor - the right realtor is worth their weight in gold, so don't discount their expertise...you'll find some awesome people to work with here on BP.Expensive - Appreciation or cashflow is your real question...what's your current job and plans for the future?

We can really shorten your learning curve and point you towards "investment worthy" options, and I have software that can filter for only STR-eligible properties to save yourself the headache and frustration of finding a property that appears to check all the boxes only to discover it's not zoned for STR or the HOA won't allow it.

The main lesson for us was that there is still a level of due diligence that our team must perform regardless of screening software.

You may also need to offer your services at a significant discount to entice people to take a risk on you. 

I am getting inundated with social media blasts and postcards from the airlines, cruise ships, and Disney offering substantially discounted trips.

You can also pull a list of cash buyers using some property data software and sort by minimum # of properties in someone's portfolio (I like to do 3 min), Min value of their portfolio to be $1M or so depending on the market you're in and that they made a purchase in the last 6-12 months to show that they are actively investing. 

Quote from @Will Daugherty: I've seen posts on here from a few years ago about rental portfolio dashboards, but all seem to be inconclusive or suggest a software subscription to have such a reporting tool.
