The rewards will come with time. 

As a seasoned real estate agent with five years of experience under my belt, I've had the privilege of guiding numerous clients through their own investment journeys.

After 4 months they give you the opportunity to open a secured credit cardAnother is called "Kikoff": These guys will report a $500 Limit Credit Line for less than 5 bucks a month.These modern services are a great place to start, they will never report late payments, won't get you into debt and build your credit score every bit as much as credit cards.After you 3 - 5 of these open for 90 days THEN apply for credit cards, you will get much better approvals, higher limits, lower rates, more rewards etc...Mortgage lenders will also be looking at how long those accounts have been open.

Flipping is a high risk high reward endeavor, especially with people just starting out. 

You can try buying ten SFRs or buy a 50-plex - the work is almost the same - but the rewards are much bigger.

@Kahlil DawkinsReal estate investing can be a rewarding venture, especially for those with less-than-perfect credit.

@Chad VerdeReal estate investing can be rewarding for you since you have commercial valuation and property appraising experience.

When I loan privately as a private lender, I have complete risk of my capital, I make all decisions and I suffer the consequences or rewards of my actions!  

Then think Risk Reward.  

That way you kind of hedge your bets (aka Risk/Reward).Self Storage is historically Recession-Resistant as it has everything to do with Death, Divorce, Down-sizing, Dislocation, etc. - things that are prevalent in normal times and certainly, in not-so-normal-times, too.However, RV & Boat Storage is similar but different, in that approx 1 out of 10 folks in the USA rents a Self Storage Unit, and that is not the case with Boats & RV's; hence it being a much more niche strategy.
