I have concentrated my research on FL and in the Tampa area, for no specific reason or personal preference...In the past few weeks, I have been in contact with an agent/broker doing this kind of work and having a team for the closing/taxes etc.. able to manage the property and all, he seems good and has provided lots of time without asking for a penny (which is the job of a RE broker, only its a lot more time consuming when the buyer is not present ...)Now I have my eyes on a property (it will be the 4th offer through him, the previous ones did not go through) and I would like to ask seasoned RE investors here a few questions...The house is advertised as a duplex 2/1 + 1/1 but after the visit I was told that an extra split had been done so it looks now like a triplex 3* 1/1 ...

They probably won’t have websites and though they may hint that they lend (sometimes they give large hints) they will not do any serious advertising.

Code pt. 1450, govern the business of real estate brokerage in Illinois.The Act, as amended, defines a real estate “broker” as an individual, partnership, limited liability company, corporation, or registered limited liability partnership other than a real estate salesperson or leasing agent who, whether in person or through any media or technology, for another and for compensation, or with intention or expectation of receiving compensation, either directly or indirectly:(1) Sells, exchanges, purchases, rents, or leases real estate.(2) Offers to sell, exchange, purchase, rent, or lease real estate.(3) Negotiates, offers, attempts, or agrees to negotiate the sale, exchange, purchase, rental, or leasing of real estate.(4) Lists, offers, attempts, or agrees to list real estate for sale, lease, or exchange.(5) Buys, sells, offers to buy or sell, or otherwise deals in options on real estate or improvements thereon.(6) Supervises the collection, offer, attempt, or agreement to collect rent for the use of real estate.(7) Advertises or represents himself or herself as being engaged in the business of buying, selling, exchanging, renting, or leasing real estate.(8) Assists or directs in procuring or referring of leads or prospects, intended to result in the sale, exchange, lease, or rental of real estate.(9) Assists or directs in the negotiation of any transaction intended to result in the sale, exchange, lease, or rental of real estate.(10) Opens real estate to the public for marketing purposes.(11) Sells, leases, or offers for sale or lease real estate at auction.

I understand that there are many other strategies to acquiring rentals but i like to buy homes that are "turn key" and most of those properties are advertised at a price that I cannot buy with cash. 

I didn't advertise on any sort of media.

I said  nothing about advertising as "fully ADA".  

I found an ad for a land lease under a metal scrap yard advertised for a 9.2% Cap which would put the value at $1.082MM (100,000 / .092).  

I just learned August 3, 2016 that alot of the campaigning and advertising we do on our own for REI becomes very expensive well with renatus when you buy any of the educational packages these things are included and i get my coaching and mentorship.

What do experienced people do when they buy a SFH in an area that doesn't have any PMs (or at least any that advertise their services)? 

Your customer doesn't care on whit about your company until you have a good looking rental unit.Since you posted this in the Landlord Forums, i'm going to assume that you are most interested in the rental side of advertising.
