Whichever way you decide to go, this is certainly a great start to your discussion.

Whichever way you go you do limit pool- but it’s your property and depends on how hardened it is against damage.

If you find a house that needs light rehab at a good price then take it....ect.....Once you have enough funds to leave your day job then you can take more risks and focus on whichever niche you like the best.

Whichever option you choose, looks like you're on a winner.

I would follow through with whichever agent brought me the deal first.

I would get the LLC setup first so you can provide the necessary documents to whichever lender you choose to work with.  

The repayment terms for a 401k participant loan are equal monthly/quarterly payments of principal and interest (typically prime plus 1%) over a 5 year term (longer if used to acquire your principal residence).Please note that if you take a full $50,000 and then pay back the loan, you can't take another $50,000 until 12 months after the first loan was fully paid back.Per the loan offset rules that went into effect with the 2018 Tax and Job Act: if you leave your job and the loan is current at the time you leave your job but then the loan goes into default because you left your job, you will have until your tax return deadline (including any timely filed extension) to make the loan current by depositing the outstanding balance into an IRA (and thereby avoid the taxes and penalties that would otherwise apply).Please keep in mind the multiple loan rules:Under those rules, the sum of the balances of a participant's outstanding 401k loans under a single 401k plan (using the highest outstanding balance of each loan over the last 12 months) can't exceed 50% or $50,000 whichever is less.

You can cash out what you spend initially in purchase of property or 70% of appraisal value whichever less.

It's the tenants themselves...I know business is business but my business decisions could/will have a strong impact on the tenant's personal lives that's why I want to understand different angles so to make sure whichever decision I make goes with my personal values.

Which of those (or whichever markets) you pick should be based on comfort levels, interests, return preferences, price points obviously, and then one of the most important is quality of the turnkey provider.
