If the numbers are right, it seems like lower-priced homes that meaningfully cash-flow are rare.

High LTV ratios often lead to higher rates, so without thorough initial analysis of long-term debt rates and market rents, investors may discover their expected cash flow falls short.For those who can secure properties at significant discounts, the BRRRR strategy allows investors to extract their initial investment and sustain their investment assembly line.

They do not provide meaningful oversight or guidance with respect to tax code compliance.A checkbook IRA LLC is an enhancement on the above structure that is generally more time and cost efficient for investors with a more diverse portfolio.

(Value added - rehab cost - holding costs of rehab and placing tenant) equals the profit from sweat equity (profit from the rehab) but if you want to extract all of the investment you need to account for LTV.  

I was sort of forced into it being a rental at the time because it was a bad time to sell (values low, not enough equity based on mortgage balance at the time to make any meaningful gain, etc). 

However if I do a BRRRR I can achieve infinite return by extracting all of my investment.

Will you be able to extract some of your sweat equity and pay off some of the HELOC.  

I'm eager to learn and make meaningful connections in the local real estate community.

Should they go under it would leave me in precarious position trying to extract the same out of a bankrupted corp.

There was a window where one could buy a property on margin in the Smokies and expect a meaningful monthly positive cash flow.
