And how we know that price is affordable and fair price with their competitor ? 

@Glenn Gillen well, what if you will never be better than some competitors?  

Would you think that re-siding a house and adding trim would be worth the investment if my competitor AirBnB listings are sometimes also NOT very attractive on the outside?

Then I'd try to determine a value add situation, can you add additional storage space/does the market support it, what are current rents compared to competitors, can the units be resized to better capture your markets need, what is the current security situation, and are their other things you can offer such RV parking or boat storage.For the laundromat:What is the current income at the laundromat, are the machines leased or owned, what are the prices for using them, how far is the nearest alternative location if you decide to raise prices, and is the laundromat the highest and best use of the property. 

At this point I've learned how to optimize online booking engines, how to deal with seasonality, how to analyze markets and competitors... why not take to a bigger deal?

Do your neighbors (competitors) have hot tubs or spas?

I have had agents and brokers from various competitor brokerages reach out with off-market potentials because they knew I could get it done, had pocket buyers etc., and could LEGALLY pay them a referral fee. 

(email that went out this morning) Besides Maxing out $Insulation to contain Energy costs and $Pressing our material Suppliers, when they say they'll beat a competitors prices, What else are YOU doing?

Look at VRBO or AIR to see what your competitors are doing.

Along with the barriers to penetration for competitors due to lack of zoning and flat land.Start small and Make Your Big Mistakes Early.
