A conventional mortgage will most likely have a due on sale clause and require a refinance to a commercial loan once you transfer it ot an LLC.

Leverage FHA or conventional loans with low down payments.Good luck! 

Conventional Loan with 3% down.

But that also complicate things as you wouldn't be able to get a conventional loan.It seems like you'll be investing long-distance.If you haven't read "Long-Distance Real Estate Investing" by David Greene, I would highly recommend it.

If it's not a deal breaker, then you can likely refinance with any conventional lender or private lender, and the current lender just has to be repaid. 

The part that goes unsaid for those that toss around BRRRR like it is some easy, push the button transaction is that most properties that would work for a BRRRR do not qualify for conventional financing.

I took out a conventional 30 mortgage on the property.

Interest rates on land contracts are usually at or above current conventional mortgage rates to compensate for the seller's risk.How much is typically asked as far as a down payment?

Conventional is an option but conventional have longer seasoning requirements and won't allow LLC vesting.

@Nick LongI think you're overcomplicating this... if it's a fixer, once it's rehabbed, just refinance it into either a conventional investment loan, or a DSCR loan.DSCR loans don't have the 12-month clock - you can usually refinance 90-180 days after purchase.
