There's too many factors to tell you off a web forum, but you should be able to figure this out quickly looking around zillow or apartments.com.

He mentions he can find out of state properties from auction web sites for cheap around 10k.

OR you have to order 'retro-fir' windows that have external fins...they slide into the opening from the outside, but they are a custom fit - add $300-400 per opening and 5-6 weeks to your time table....but then no exterior trim and a little on the inside... 

I am thinking of putting external burglar iron bars if insurance allows.

Definitely use an external pricing tool like Pricelabs, consider allowing pets with a fee (an extra $5-8k per year just might make the cost of that new rug more palatable—and it’s unlikely you’ll need one since most pet owners take care of the place), and consider one-night stays if the guests are properly screened.9) Others will disagree and perhaps location has a part to play in areas that are and are not desirable for partying, but to elaborate on the last item above: one-night stays (between other guests) add about $10k NET to my annual bottom line.  

My specialty is in the IRA arena not web marketing. 

If you're not doing ACH and only have a few units, the web-based software is free to use.  

Make sure when you are evaluating custodians they have an interactive web site with a chat function so you can get answers right away.

I've used both web and desktop versions.

Like the "retirement planner" every brokerage house has on their web site.
