Hopefully this can be helpful for anyone looking to learn the basics or refresh their memory :) CONCEPTS1.

Heirs can inherit Roth and the gains remain tax free PLUS the heir(s) didn't have to pay taxes on the principle.5.

I am a strong advocate of those same principles, but the real estate you are targeting cannot realistically absorb types of licensed and insured vendors your desired systems require to be effective. 

Listing platforms are great for exposure, not final screening, especially once you operate across multiple states.A few principles that consistently hold up:Control the applicationSelf-reported income is a placeholder, not verification.Treat anything typed in by an applicant as unverified until proven otherwise.Why paystubs and bank statements fall shortPDFs are easy to edit or purchase.They show a moment in time, not income stability.Once you interpret documents yourself, the risk shifts to you.Better income verificationUse direct-connect tools where applicants log into payroll or banking systems themselves.Data comes straight from the source, not uploaded files.You see employment status, hire date, pay frequency, and real income.Reference calls are unreliableMost are coached or selective.Ownership and contact details should be sourced independently, not provided by the applicant.Background and eviction checks need layersSingle databases miss records.A cascading search tied to address history catches far more issues.Human review still matters when data doesn’t line up cleanly.What a solid workflow looks likeOne secure application link.Identity, income, criminal, and eviction checks run together.Pay for what you use, no subscriptions.A little friction upfront saves a lot of value later.

Now it's more like flip four, buy one - but the principle is the same.

Part of your mortgage payment goes towards principle: your housemates are paying down your loan for you and buying your property for you over time. 

The same principles hold true across a wide range of real estate sectors — including industrial, flex, healthcare and medical, student housing, retail centers, land, and specialty assets like sports and recreation facilities, among many others.The core message is exactly what you described: real estate investing should be approached as a toolkit of strategies, not a single-asset playbook.

A few of the principles I've learned over the years that have contributed to this set up:1.

Did you confirm the 2% annual management fee is deducted from principle prior to principle being returned? 

The properties that have performed the best over time were actually negative cashflow when I picked them up, but thanks to principle pay down, rent increases, and appreciation those properties have greatly outperformed the ones with a few hundred bucks in cash flow upfront.
