Yes, representing yourself in a transaction will turn sellers away but that shouldn't deter you from finding the best method for your area to get passed that. 

I understand the disclosure of such information to any prospective buyers but I'm interested in receiving input from agents and investors who may have some insights on the pros and cons of pursuing this type of an investment.

As mentioned, no show prospects really set me off. 

If a prospective tenant is in a rush to move, usually it's a red flag unless they tell you upfront why they need to move.

If the intent is not to put the house under contract and continue to accept more offers, and to fix the house up to show it to prospective buyers, I would be concerned.  

If they won’t do that I let them know they may be subject to additional costs for collections, and that will hurt their future prospects for rentals as well as other credit based opportunities. 

At that point, if one of the investment property owners decided to sell would prospective buyers (assuming the prospective buyer would live in the unit) qualify for a warrantable loan? 

Prospecting for investors as a scout I presume?

This is because it was purchased to be a good home and not necessarily a good rental.If I were to invest OOS:I would not choose the highest cash flow Midwest locals but would look for a location with increasing population and constrained in some way in their RE growth prospects. 

If you insist, you will want to talk with the park owner before proceeding as they make the rules there and will have the power to approve or deny your prospective tenants.
