My remote controller seems to be going.  

My primary plan in this market for this type of asset, is to buy out as many tenants from their extremely under market rent controlled units, do improvements and re-rent at market and dispose or refi.

Newbie, looking to purchase a single family home near Navarre Florida for a long term rental, buy & hold for cash flow.I do not live in florida, so I am looking for advice on things I should be wary of before buying, like paying for pest control ( we do not have Palmentto bugs in the midwest, but we make up for it with big mosquitos), sink holes, mold...Any things I should take into consideration before buying in the sunshine state.

Both cities just enacted some rent control legislation you'll want to make yourself aware of, and there's plenty of good forums going around BP about that. 

I generally don't like the idea of borrowing against a 401(k) for any reason mainly because of risk that the loan will be called due to something outside of your control like losing your job. 

Just get control like you you were thinking is my bad advice.  

And just general rent control.

I have a Solo 401K with checkbook control for the master account.

I agree, but if someone is a KP and signing on to the loan they would want some control in deal to make sure the deal doesn't go under and ruin their credit.

The unit itself worked well for temperature control.
