Knowing my timeline, do you think it's feasible (and wise) to start by going hard-core into wholesaling, then build up into fix & flips (for fast profit), and then rolling all of that income into buy and holds with the BRRRR method? 

Make the initial purchase personally under my name, secure financing under my name, then quitclaim the property to the LLC?

Mortgages are the customary security instruments.

The act wasn't intentional, but should I still approach them about paying some of the bill or taking a portion of the bill from their security deposit?

Hi  everyone First time using the BP calc , so perhaps I am just not understanding BP method or I am miscalucating however ,, I input a home's data points with all associated costs and the complete  loan amounts, points, fees etc.When the results came back , The ROI was based on the total project costs.. i.e.  

Be sure you’re getting estoppel letters signed by each tenant indicating their current rent and security deposit along with leases.

For this reason same configuration units in multi buildings rent for much less than small detached houses of which there are many.1-4 unit properties are valued using the comparison method. 

This method allows you to reach out to the BP colleague and ask who they interviewed with, who they decided to go with and if they like working with their CPA/Attorney.

I know most of the time they look at the security rather than the individual, but if you built rapport with loan officers or liquid individual (for lack of a better term) can you attain cash quickly this way?

You need this for your records to protect yourself in case the tenant claims they paid the old owner.Make sure the security deposit 100% transfers to you.
