MTR is treated like an LTR from what I understand and I already own a couple LTR's so would rather do more of those than an MTR and avoid the extra hassle of furnishing, etc.  

One thing that male flippers sometimes overlook is making it not just a house, but a home and giving it that extra touch that makes people want to live there.

That's an extra $250 per month or $3,000 per year.

Also seller might need some extra days to move out.Details, the house has been on the market for over 170 days, fell twice already, the seller prefers a cash buyer, how to negotiate with this type of agent?

I have never had any tenant object to paying an extra $35 per month to have the softener, that is about what they cost to rent from softener companies.

It's not worth the extra monthly income that comes with getting involved with low income renters.

The power differential is real and you are helping equalize the playing field  The reality is if you are an ethical and consistent strong performing syndicator/GP, you should be extra supportive of this.

For instance, one property seems to have an extra bathroom that is not listed in the county records.I plan to make some modifications, including removing a closet wall to expand a bathroom and taking out a kitchen island that contains electrical outlets and a switch.

Unfortunately, it was on the Monday after our vacation ended and I couldn't get the extra day off.Anyone have experience with Sheriff's sales? 

Quote from @Bruce Woodruff: So that's 7 months......now investors will have to add a bit into their flip budget to cover the extra 3 months (or so) holding costs... will make overall costs go up though...
