I feel like I'm uniquely qualified to answer this question. 

I think my strategy has been successful with my two current STR's by providing something different and unique.

@Joshua SlattonAlthough every loan is unique and each lender varies with their requirements, one would find that these items are consistently what make up a comprehensive loan package.

Renting, Refinancing all have their unique challenges as well. 

Each property will be unique based on number of units, location, etc and I would suggest you find a Realtor to work with that has experience helping clients buy rental properties.  

The needs you have, your age, your goals, your desire to be active or passive will likely determine much of the balance of the funds use.No two of us are alike, you are unique and as such will have unique needs and wants.

In the case of the one he listed for sale, the owner simply chose too niche of a property, and miscalculated the ARV based on several factors unique to the property.

The location is great it is a unique street that actually has no street only alley ways to the homes and front of the houses is a large courtyard with sidewalk next to the local night scene.The other way to do this flip, the house is in good shape could do bare minimums redo the bathroom and kitchen and simple cosmetics items.

I'm looking for a bit of advice in my unique situation.

Any help with this unique situation is much appreciated.
