I think a $200-$250 increase in one shot, would severely aggravate the tenant.

Is Bi-weekly worth the aggravation?

However I will also say, you will work/pay for those higher returns with issues and aggravation.

I find a lot of sellers who aren't serious investors tend to just 'ballpark' what they make, which can be a bit aggravating for clients that seek in depth info.

The only reason she would file a complaint is to aggravate your business.

If they stay they will continue to cost you money and aggravation. 

I have found that the times that I have made complaints (mostly about lender/title companies) the fall out/drama is not worth the aggravation.

Does anyone have experience with giving tenants small gifts as a way to smooth over aggravations from unexpected renovations while tenant occupying the property?

There are so many unknowns here that carry big dollar amounts (rehab needed) and aggravation (evicting tenants that have probably been living rent free while the foreclosure process has been in action).My guess, is you're going to "get what you paid for"....and then have to pay a lot more. 

Castle Doctrine while fairly easy to read has lots of big lawyer words like forcible, aggravated, unlawful, deadly force, kidnapping, sexual assault.
