Do you have the financial strength to hold/carry these lots if they don't sell quickly? 

Moves risk to be financially covered by insurance hypothetically.

most of these "youtubers" etc social influencers are nothing more than paper tigers.

@Kris Lou Be careful with agents as 95%+ of them really only know how to handle owner-occupied transactions.We don't do biz in Indianapolis, so this is unbiased info we hope you find useful:Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

However, sometimes investing is more than just the financial return.  

I doubt many are going into credit card debt or if they are that's kind of crazy.. as this part of real estate has no smoke and mirrors generally.And I suspect because most of these folks are doing some sort of PPM and need to deal with accredited investors.. that separates those wanting to start to those who have already had some financial win's or experience and just looking for a new avenue.. 

Staying local and house hacking—especially now, before kids—gives you so much flexibility to set yourselves up for long-term success.Your financial foundation is super strong, and house hacking a quad sounds like an amazing first step for you two.

@Ryan Fox it's important to make sure you understand the pros and cons of rental arbitrage to see if it meets your personal investment and financial goals. 

There’d need to be a lot of rehab work/managing that would require you to put in that many hours.From a financial perspective, it seems like the highest leverage way to keep buying more properties is leveraging your W-2’s and then being work optional.

Just stay flexible and be ready to adapt to market changes or your own financial situation.
