Unless you're concerned about value for resell and/or debt refinancing, I think many prefer that sector of the market.  

Refinancing the BRRRR with no income will be nearly impossible if you're just starting out.

So, in the last 4 years this is what I have accomplished;1) flipped around 12 properties2) bought into 5 plex in Lebanon 50/50 with my son for $375,000, rehabbed some and increased rents to market.3) bought into 8 plex in Forest Grove 50/50 with my son for $642,000, rehabbed all 8 units and at market rents.4) sold 5 plex in Lebanon by owner for $545,000 and invested into Crowdstreet Opportunity Zone in Atlanta, Ga.5) bought fixer 4 plex in Albany, Or rehabbed, and rented at market6) bought 2 fixer 4 plex's near Western Oregon college campus, rehabbed, and rent at market.7) started hair salon, pretty much failed, and got rid of it 3 years later.8) refinanced 8 plex and pulled out $100,000 on my portion to pay off debt.9) Majority partner refinanced 72 unit building and received $145,000 I used towards debt.I accumulated lots of debt during this 4 year period, using my HELOC for down payments and rehab work to get to market rents.

@Jared Wild I mean I would sell but I’m refinancing this extra income and interesting in investing in some large apartment complexes

I recently refinanced the mortgage on my primary residence and combined the loans I took out to purchase my investment properties.

My follow up question is, so if I were to be doing a buy rehab rent refinance on a property would you recommend paying down payment with my own cash and getting a fixed rate 30, year loan, using hard money for rehab, and then refinancing after that?

I’m debating how much equity I should hang onto when refinancing a property where I own in cash.

Each Bank/Lender has a certain seasoning period, in which the home must be owned before refinancing. 

I most recently refinanced $3M with him a few months ago and had no issues, and our relationship goes back 6 years.
