Professional real estate investors and property managers always conduct a custom "rent survey". 

Don't underestimate the impact of that - I get a lot of prospective tenants who tell me that the other places they've looked at - sometimes at higher $ - haven't even been cleaned, let alone updated. 

Second, "rules" created would apply prospectively not retroactively.

Eventhough they will charge you they are usually worth every penny.Always remember to do a math analysis and try to look at the subject prospective properties before you make an offer or at least have a clause in the sales contract that allows you the time (usually 10 to 15 days) to make a detailed inspection and possibly back out of the deal without a penalty that hurts you too bad.  

STR's don't care about what they can't see, and meanwhile, I can take my time to do it right.You will be focused on customer service, which is not like a traditional property manager's job, honestly (I've been PM'ing for 20 years so I am aware of what goes on).

All of my adult working life I've been stuck and complacent in the customer service/retail/sales industry (not the rewarding kind of sales).  

One prospective applicant seemed great in person - very friendly, polite, punctual, gainfully employed, etc.  

It depends on where you are in the project and how extensive of a rehab..Too soon might run potential prospect off..

Conventional, Hard Money, and Portfolio/Commercial lending are the 3 main methods.Conventional lending is going to be mainly the "buy-and-hold" type of customer.
