I'm focusing on deleveraging right now, mostly for my own personal reasons and lifestyle simplification.

I would consider either full management or self management depending on your lifestyle, etc.

They lived a fine life style, but not far above the lifestyle of lay people.

Its a lifestyle cost like food and travel or anything else.The only truly depreciating asset you have is time!

Many are chasing FIRE lifestyles, W-2 replacements and a stable monthly income where they can "retire" at 40 with a monthly nut of $10k.

Its like any sales job you have top producer and you have those that just are not cut out for the industry lifestyle or sales etc etc. and this is for many reasons. 

I think you need to decide what lifestyle you want and go from there.

Assuming you haven't gone crazy in the lifestyle department, I'd think you could handle the debt to income ratios handedly.

Reading J Scott's book on rehab costs helped tremendously on being realistic with your numbers.Stayed frugal with lifestyle costs, kept wholesaling for around 2 years before buying a fix and flip, then rolled my profits from that into my first two rentals which were conveniently on two side by side lots and sold in one transaction. 

If you are willing to shed some light on your philosophy behind your practices that would be even more helpful.I am working with the rough idea of [12xPITI + 1 month's rent + my insurance deductible] as a 'formula' for my reserve fund goals.Something I am considering is taking my cashflow and splitting it in half. 50% for me to enjoy now and 50% for reserves and to build funds for future properties.A little back story, I am investing in real estate to subsidize my own lifestyle, a freelancer/traveler.
