The main reason we screen potential tenants is to get the highest possible chance we can of getting the rent in on time.I would not make a problem out of a peaceful situation.my $.02Others may disagree.

I would examine the money you have left after your PITI.  

[Yes, I disagree with Jeff as far as BEST use of your cash].My biggest question to you is: what are those two options REALLY worth?

Account Closed I disagree a little bit with your #2 point.  

I think spreading them out over a longer period of time may be more effective than 6 in 6 months - others may disagree.  

Doesn't this completely disagree with the whole mantra of "we buy houses cash fast?"

I say this as I am new to real estate, but I disagree to a certain extent, the key is to take the cash from flipping and diversify it, tying all proceeds into rentals is not going to work today. you see my goal is to flip to bring good cash to purchase other real estate and small service businesses, now I've used the funds to the fullest and now have multiple streams of income, to only rely on rental income unless you have large investors or large amounts of cash is setting your self up for failure, if you diversify the proceeds into multiple cash flowing businesses and properties now your building stable wealth. an example, I know I can purchase let's say 80 loan accounts for 30k, I can hire 2 guys to cut the 80 lawns in a week at approx 11k in monthly income, that's 110k income for 10 months, not bad from 30k profit off a flip to now a steady 110k income. the same goes for several service business you can buy them cheap and make a great roi off a small investment.

Most of you are going to disagree with me on this one but especially to Sororities (and sometimes Fraternity's).

The day before I listed it, Zillow and Trulia (both owned by the Zillow Group) disagreed with each other by $60,000.Zillow's own website says that 80% of their Zestimates are within 20% of the actual market value.Heck, I've seen them list properties that don't even exist. 

If your gain is greater than the 121 limits  you could examine your intent as @Thomas Castelli said.
