I can see many people's recommendations in the other thread being focused on house hacking, which makes sense to me. 

I’d love to hear any tips or strategies that have worked well for you in real estate marketing, especially with PPC campaigns.For those who’ve done this successfully, are there specific keywords, ad placements, or campaign types that you recommend?

I highly recommend you start going to meetups.  

We don’t know any PMCs to recommend in the Cape Coral/fort Meyers area, but since selecting the wrong PMC is usually more harmful than selecting a bad tenant, you might want to read our series about “How to Screen a PMC Better than a Tenant”:https://www.biggerpockets.com/member-blogs/3094/91877-how-to-screen-a-pmc-better-than-a-tenant-part-1-services-and-processesWe recommend you get management contracts from several PMCs and compare the services they cover and, more importantly, what they each DO NOT cover.

The bottom line is this: Concealment is not asset protection, proper (time consuming and expensive, I know) management, and good, prudent, practices (ditto), WHICH ARE ADHERED TO, and insurance (expensive), are needed for asset protection.

Since it is your first I would say all the above are great recommendations. 

Some will follow staff recommendations almost all the time .. others will not..

If you're willing and able, I do recommend the "house hacking" strategy which is just a fancy name for buying a rental property and living in one of the units, because you'll get very favorable financing - an owner-occupied fixed-rate 30-year mortgage.I'd also say, analyze that property as if you won't live there and it's a pure rental, and make sure the property is still cash flow positive if there's a tenant in your unit because then you'll know if it's actually a good investment.And when you analyze it, include payment of a property manager in your #s because if you don't, and doing so would make it go cash flow negative, then you've just bought yourself a job because you literally can't step away from managing it without losing money.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

I would recommend opening up a brokerage account with Schwab, Fidelity, Vanguard or any other large firm like this.
