You already have done it before, and will be more experienced in finding another home to add to your stack.The current interest rate environment sucks for BRRR'ing.

We have a safe environment on the emerald coast and a strong job market.

This will force some out that would have been purchased under the previous system.In the end, I don't see this as a major problem but I suspect it will cause more friction and decrease the overall satisfaction of both buyers and sellers for the next few months as we get used to working in this environment.

Definitely do HELOC esp in this right rate environment so you dont pay on the $ from Day 1 and it gives you the allowance to find your next home at your leisure.

Reason #4 is that we are still in an environment where housing supply and inventory remain limited.

Scaling to a property count is foolish especially in this environment, scaling to portfolio value(while leveraged) is the key. 

So, do operate within the BRRRR environment in an efficient way and not under such stress and pressure that means having enough money to front the contractor like 20% of the rehab. 

Also, in PR, having a local facilitate that exchange - who knows the environment, smooths the way so much more.

Additionally, you are correct about the potential appreciation of a condo in this environment. 

House hacking is an awesome way to experiment in a relatively low risk environment.
