I know in Virginia my friend had a similar issue (side-by-side duplex, though, not second floor) and he was not proactive, just warning them several times verbally.

No reason not to use a top platform.Regarding the friends thing, that is dirty pool IMHO.

Yeah I have some friends that have properties they hold in New Orleans and have heard the good and the bad.

Another good strategy is to connect with a local property manager that does real estate sales, or can refer to an investor-friendly agent. 

I will provide some thoughts on the San Diego purchase- virtually all high LTV mls purchases since rates started to hike have negative cash flow at purchase- historically great appreciation- historically great rent growth but recently flattening- prop 13 is great benefit for long holds- laws keep getting less LL friendly.

High LTV purchased at retail (off mls) has large initial negative cash flow- regulations are tenant friendly.  

Your relationship with an investor-friendly realtor will be crucial here.4.

God speed friend!

One big thing to keep in mind is that Daytona Beach itself is not very STR friendly.

I also have a friend/sub-contractor with 40 years experience in all areas of construction who works with me on most of my deals for low cost labor.
