Negotiated to 25% but paid supply fees for restocking toilet paper, paper towels and the like.

Have soap and towel, face masks , you dont know how the tenant lives . 

Sorry I meant towel.

Make sure you account for all soft costs during construction and financing--are you going to require permits or variances to change the use to 14 units? 

I didn't see you account for soft expenses for the rental.

It would be best while working with the lender prior to getting into contract on the property to do a soft credit pull. 

Balance the academic learning aspects with the personal development (soft skills) side.

Sometimes they don't respond at all, but sometimes I'll get feedback such as "well, your mattress was too soft for my tastes" or "the neighbors two doors down were loud" Normally its nothing that can be helped but I always like to apologize and thank them for feedback....maybe in the future those people will realize the items they are complaining about are out of the hosts control and leave the 5 stars anyways.

As long as you chose some “middle of the road” hardness, that’s probably all you can do - you just have to accept that someone might find it too soft or too hard occasionally.  

Make sure you are being nice, (a soft answer turneth away wrath) just being nice will go along ways!
