I have a little over 100k to get started doing the BRRRR strategy in the markets of Cleveland and/or Memphis since my primary goal is cashflow!

My understanding of the strategy is that you would find a good investment property, increase its value and stabilize it, and then refinance.Pulling out cash from your primary residence tax-free can be great, as long as you are getting a better return than the additional interest you are paying.

More to your specific questions though.....I own property both traditionally outside of retirement accounts and inside of SDIRAs and SOLO401Ks (better IF you qualify).  

Then sell at 5 years to meet the primary residence requirements. 

But as I stated this is no 2010.. this is a new day.. the big wholesalers that provided inventory to my turn key company I was funding in Orlando or instance they are out of business.. so it the turn key provider.. simply not enough inventory for that model to work.now to be fare they are real estate brokers which in most instance the law demands.. and so they just switched to  traditional real estatethis is why wholesaling as taught by guru's can be a dead end street.. once it peters out like now.. what do you do?? 

I will be acquiring the property as a primary residence so hopefully I can find someone with a reasonable LTV and lower down payment.

I am new to Real Estate Investing and currently own one single family rental in Colorado Springs which was previously my primary residence while stationed in Colorado.

as your primary you should be able to get an O/O HELOC my guess on the move out question would be dont ask dont tell, so residential HELOC's tend to be 10 year term, so I would maybe get the HELOC from a bank you dont do investing related banking with maybe an out of area bank or bigger institution. and set up a P.O. box or a different address to get correspondence from them (totally reasonable in a multifamily) this way when you move that doesnt change, so no red flag for them to call it due.

A credible appraisal would likely present both income and sales comparison approaches, with the primary being the income.
