Due to being located in such an expensive area, a conventional loan requiring 20% down seems almost impossible unless I want to wait years.

Impossible to answer that without knowing your skills and goals.

Though, those are almost impossible to find.

Not impossible, but not easy.Add to all this a 3-6 month timeline, I am going to say it is probably pretty unrealistic.  

However, the lien clouds title and makes it impossible to sell or refinance until the 120 days expire.

However, I'm sure I'll be hearing from the group that insists that prices are going to increase another gazillion percent in 2022 even if rates are 6-7%+, and that a crash of the housing market is impossible.

@Jonathan Taylor@Dave Skow Yes, it is virtually impossible. 

The problem you may run into is that with rates rising like they are it'll almost be impossible to refinance into an IRRRL.

So I have some experience flipping but I am transitioning into the rental landlord aspect of real estate I currently recently purchased a duplex that came with a Efficency making it 3 units I am renting out I have 30k but I live in Miami where prices are unbelievable I know I want to s ale up from 3 units to maybe 6 units but finding that in Miami is impossible so with that being said should I just get another duplex FHA?
