How feasible is it to create a "standard" floor plan that you can simply tweak as necessary (or just use one that you've used before)?  

It is important to setup your company correctly and you start by following the Easy Step Interview.After that you can tweak QuickBooks through the Preference Section to fit your own personal needs.You will setup your Properties as a Class in order to keep track of income and expenses per building (SFH) and per unit (Duplexes, apartment bldgs., etc.)When you setup your Properties as a Customer as well, you are setting them up to let you know where each tenant lives. 

I might have to tweak my search criteria slightly to find a home considered more move in ready, just in need of updates.

Agreed those are risks, but think you could target your audience and tweak lease terms to minimize.

We're gonna dive in and start our mailers...tweak as we go monthly and see what turns up.I'll keep you posted.

You will need to tweak a little here and there to fit your market as well as marketing budget.

Unfortunately, no one has a crystal ball, so it is all guess work, and for somethings, say cap rates, a small tweak in one direction or another can totally change those numbers for better or worse.

Theses are a few simple but effective tweaks that you may be able to make (in addition to the other things people have suggested here) that can help you get that property sold. 

. $20 is fine to go meet and greet, get their numbers and contact them individually to get to know others.I see meetings posted where they say there will be no pitching by some speaker, well, not entirely true as the speaker doesn't speak to hear themselves talk, they clearly have expectations of business to be had, the pitch just comes later after they tweak your interests.......that's fine.Going to some meeting where you have a bunch of old RE types there, understand that what they may teach or talk about is what they have been doing for 20 years, you'll get outdated, often unethical or even illegal stuff if these guys don't change with the times and stay current, it's hard enough getting Realtors to stay current, much less some old landlord or rehab guy.

The main cost for websites is in design so if you aren't as worried about high-end creative you can get away with tweaking the free theme a little to suit your needs.
