For those of you collecting rent by ACH, are you requiring per lease terms the tenant to ACH on the rent due date?

A good property manager will treat it as a business, and not as a charity.

Using your example of $100K net, assuming that you are sole proprietor you can contribute about $36K.You can't defer gains via 1031 exchange on a flip so the rest of the funds will be taxed, unless you find another way to minimize your tax liability such as donating to a charity...

While I understand the value of long term tenants and prideful renters, I don't run a charity.

You're not a charity offering free housing and need someone who will abide by their lease and pay you the rent.

Remember, you are running a business not a charity.

(golf tournaments, classic car show, a charity, or other Spring time events) I've watched Million Dollar Listing before trying to get ideas, and have seen them do wine and cheese parties, other tie ins with businesses in the neighborhood, etc.. 

I can't afford to be a charity that revitalizes neighborhoods.  

Sponsoring a sports team is likely viewed as a charity donation.

It's about what the money can bring - the lives it can change, how you can impact the world.If $10,000/month is too easy - then set $100,000/month goal but give away 90% of that to a charity like @Jay Hinrich's "A Heroes Home".
