If it truly is an issue to protect the structural integrity of the home and you think they will be there long term I would explain that you don't want to have to have the yard ripped up to do foundation repairs.

Some proper pre screening over the phone will eliminate a lot of no shows.Listen to the podcast below and it should answer most of your questions:http://www.biggerpockets.com/renewsblog/2014/08/14/bp-podcast-083-landlording-integrity-marcia-maynard/

I have the firm belief that if you are doing the right thing and treating people right and acting with honesty and integrity, then the right thing will happen.

By purchasing these homes as well as off market homes @Madeline J. can make a positive impact on these neighborhoods just by being an investor that is diligent and respectful of the neighborhood.No matter what neighborhood she buys in here there will be a fantastic impact as long as the rehab is done with integrity and improves the overall value.  

Keep the integrity of the area as a kitchen- just don't go overboard with appliances.

Wonder if they've started integrated into a North American credit system, any?

It looks like both are possible through integration with the Google Hangouts app.

FYI - When using QuickBooks - you do not need any overlay for property management and accounting.Unless you are looking for screening tenants, posting to online sites etc.Agreed Buildium, Propertyware (great with integrating with QuickBooks), Appfolio are few good software and many more where we helped our clients. 

This also helps me in ways that, when I present to a prospective tenant or a tenant that I am presenting a rental increase to, I know as much as I can about my market and no matter where that tenant goes to look for other comps, I will have presented my property to them with integrity and can show them why my rental is a great value.I hope that helps.
