This is the first time I have used internet advertizing and pulling credit scores.  

Has a shared coin operated washer / dryer in the building common area.It is in a C class neighborhood, built about 1970.Purchase price was 470k,  plus about 10k in closing costs and I will put about 10k into repair/improvements.At possession on May 1st only 1 unit was rented @ 800 - the tenant has been there 1.5 years.I believe the market rent should be more in the range of $950.I put an advert on Kijiji saying there would be an open house on May 4th and got about 35+ people replied. 

If you have repairs or a turnover, you will have other expenses, but they should be clear (eg advertizing, leasing fee, etc)

I did a lot of business with the San Jose RIA and the old owner she sold to a turn key provider.. the turn key provider wants the SJ RIA for profit and to sell her product of that I have no doubt. and the bigger turn key providers in the mid west spent a bunch of bucks getting into her RIA and being allowed to present they spent it in the form of adverts in her magazine...  

Make sure you are adverting your property through as many free places as possible.

Last September we advertized a house for rent for $750.

I am not sure how to advertize this as an option out on the market.And is something like this fairly common? 

If you advertize at market value, then you won't ever be renting to any of their clients as you can state the rental price is firm. 

So, from the point of view of an investor who has a vacation rental and was looking for a vacation rental PM, I would say that you need to go out there and advertize.
