I am thinking of borrowing against my investment account to purchase a rental outright. 

I am currently having my finances analyzed to see how much I can borrow on my first deal.

Jeff Dulla not all borrowers qualify.

Makes hard money loans look like borrowing straight from the FED.

You've borrowed for a car.

C Corps is simple - just issue additional share.Transfer of memberships of a C Corp is cumbersome - whereas for a C Corp all that is needed is to transfer the shares.Control of a C Corp can be altered without any transfer of shares - just dilute the shareholding by issuing additional shares.Long term capital gain occurs when shares are sold (after 12 months).Ask the CPAs to find out details of medical deductions, and how to use 401k to a) reduce employee tax, shelter corporate profits, retain earnings and transfer LLC profits to a tax friendly state via management fees to the C Corp.Banks do not like LLCs as borrowers - Finance is more easily obtained by C Corps.

I would have dozens of interested borrowers if what you are saying is true.

I would love to hear success stories or pitfalls people faced.Based on my numbers it seems like I could potentially borrow much more than I have in to a property.

Obviously borrowing money increases you % returns cash on cash, but I have a couple rentals that are completely paid off and reading the forum is making me feel like I'm doing it wrong and should be refinancing and BRRR'ing the properties.
