@Shaun Ortiz - I did BRRRRs single family homes, but transitioned to multifamily... not necessarily to get away from BRRRR investing, but to do it on a larger scale.

I put roughly 20% down on a $200k home, and am curious what steps I could take to possibly turn my original investment into a large portfolio within the next 10 years, when we're currently "low on liquid funds" after finishing up a wedding.... 

The main reason that I like the larger units it that a 4-plex ranges from roughly 1-1.5 million in my market. 

Lenders typically look for experience, liquidity, and a solid track record when funding new construction projects.

This means for larger ticket items they will cover some maintenance or repairs on them. 

Often, I am not able to keep all of my ira funds invested in active loans so I would like to be able to keep the money that is not invested in loans in a liquid "money market" type of fund on a temporary basis.

This means the rental rates are average nothing to write home about, but the increase you'll get in appreciation is amazing, but not liquid until you sell. 

The other two are much larger with much larger investments from me and profits on one of them in the 8 figures for my clients..

You will need 6 months worth of the payment (including taxes, insurance, HOA) in liquid assets to show an underwriter.Now with doing a rental agreement, do I need to have tenants living in the home first or new prospects lined up before the underwriting? 

There are two basic models - the traditional larger 50 - 100+ bed facilities, and a trend towards converting SF homes into 6-10 bed facilities.
