Occasionally there is some fluctuation, but I rarely find it difficult to find good tenants other than a seasonal issue around the Thanksgiving/Christmas holidays.

The FMV is $170K to $180K, not 100% where this will fall until owner gets appraised because of the market fluctuating right now.

Can use as a "guestimate", I would set aside 15% of that total for the unforeseen and fluctuations of accual cost vs the guidelines.

Sure, CAP rates are going to fluctuate with interest rates, they have too. 

I do have a renter in there now for 16 more months, and am more than willing to wait out the storm of fluctuations with home prices.

Another income point is that loans are done when sales are slow in refinancing but the mortgage market fluctuates as well.You may excel quicker as a Realtor, if you're good, getting into higher incomes as a mortgage originator take time as you're more of an captured employee.  

Mine fluctuates constantly, never more then 3-4 months at the same amount.I'm not aware of HELOCs with fixed rates, i thought they where all a variable interest rate product.Here is a post to exactly how I use my LOChttp://www.biggerpockets.com/forums/48/topics/100685-here-is-how-i-do-it-please-critique

It's hard to answer your question regarding what rates are because there are many factors that go into what your rate will be, and rates can fluctuate throughout the day.

(We're not discussing seller financing, below market financing or assumable financing here, that's a whole another discussion vis-a-vis the relationship of value to below market financing.)What the Professor is saying is that real estate values have NOT increased in "real dollar", when you exclude inflation from that equation.Once upon a time, a long time ago in a distant land, the distance measured in a few miles, before the current real estate crash; I discovered several pockets of real estate that were somewhat isolated from market fluctuations in value.

They tried to justify using the 7% rate because "the rate could fluctuate from now til the time the loan funds."
