The goal of a MF sponsor/syndicator (typically) is to return their investor's money within 5 years and deliver IRRs in the north teens or low 20's if you're lucky.

I have been experiencing awful conditions as a buyer, expected to pay record low cap rates AND accept giant material defects, quickly and with cash!

But I'm wondering if there is a better low-risk option for that money, which is just sitting there for a rainy day, that would help it grow on its own over time and allow me to withdraw funds as needed.  

I’m attempting the BRRRR strategy but can’t refinance for another few months due to having low equity in home.

I personally wholesale lease options, so I can work with low/no equity leads, and recommend everyone learn how to do that too.As for other marketing.

Like, super low.

This is just a theoretical that popped into my head, but for those markets where rents are relatively low, would it be reasonable to take on a tenant with the typical one month's security deposit, but in addition you add $50 or $100/month to the rent to build up the deposit till it hits two month's worth?

There shouldn't be any money due from you unless the fee the seller's agent pays is unusually low. 

@Jon RolandHave you looked into Brandon T's book on investing investing with no and low money down?
