@William DeLucaRefinancing out of the BRRRR is going to a bank or financial institution and securing a mortgage.  

is your investment secured by the property?  

Maintenance and security deposit stuff (usually on maintenance they keep a retainer and don't bother you unless it's over $300)4.

@Vivek ShahBack in 2017, Fannie Mae quietly announced a change that allows transfers to LLCs under certain conditions:"The mortgage loan was purchased or securitized by Fannie Mae on or after June 1, 2016, and the LLC is controlled by the original borrower or the original borrower owns a majority interest in the LLC, and if the transfer results in a permitted change of occupancy type to an investment property, such change does not violate the security instrument (for example, the 12 month occupancy requirement for a principal residence)."

Granted, I do look young for what i'm doing; how do I handle or show my competency as a new investor? 

Buyer’s obligations under this Agreement are NOT CONTINGENT upon Buyer securing any financing in the purchase of the Property.

A very good friend brought a realtor who specializes in this type of project, her buyer had been working on this for several years and fell through and so we were able to step in after most of the water rights were secured.

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

*I improvised and gave her the cashiers check first, it was still blank, for her own security so that she felt comfortable signing Warranty Deed etc. - Notary witnessed too (I'm winging it here!). 

Don't threaten to keep the security deposit.
