There are definitely options here.

Im located in Phx,Az and its common here to still see empty dirt land in prime areas of city, as an example, my father who knows next to nothing about real estate purchased a 7k sqft gated dirt land  in the city 3yrs ago for $35k cash, was planning to invest in it but it was too much hassle for him so recently he sold it for $140k .What's a good way to find good deals on empty dirt land  in the city or close by, does mls offer this search option.

You should be getting $1,800+ in rent based on the duplexes we manage. 

I assume if you are a reasonable person you would select option (a).

I'm based in cape coral and have majority of my portfolio here... you are right on cashflow and I will add appreciation and population trend is planned to be increased due to this city is one of the cities used as an outlet of miami, Orlando and Tampa since they are too expensive... happy to chat whenever you want.

The two options I am looking into are House Hacking and Wholesaling. 

If not, or if this is a first time occurrence, I'd start with gathering any tangible proof that the damages are a result of the other landlord or tenant ie; video camera, pictures and suggest to the tenant that they seek a resolution based on the evidence.

Here’s a detailed analysis to help guide your decision:Initial Costs:Purchase Price: $260,000Down Payment and Closing Costs: $60,000Monthly Cost: $400 for several yearsMarket Value:Current Value: $540,000 to $600,000Immediate Equity: $280,000 to $340,000 (based on the market value minus the purchase price)The substantial equity in the farm can be a powerful tool for your investment journey:Home Equity Line of Credit (HELOC): You could use a HELOC against the farm's equity to fund other investments.

They know what the rental rates are, tenant base, etc. 

That’s crazy that there are so many options that renters have the ability to be that picky.
