I will be recasting my old mortgage to the new property.

Short answer is as little as possible.The long answer is it depends on the deal.Typically you end up in a subject 2 situation when the current owner has little or no equity in the property, the current advantage of subject 2 properties is that most mortgages are below current market rates.Keep in mind when acquiring a property subject 2, in most instances you are not notifying the current lender of the change in ownership, and most if not all mortgages have a due on sale clause, which is the lender's decision if they want to enforce it or not.I personally like the idea its a great way to get investment properties with low rate loans, that with most likely appreciate in the coming years.

Among 225 corporate real estate executives surveyed across the U.S., Canada, and Latin America, 38% expect to expand office space over the next three years, up from 20% last year.

We look at the area, capex, rents, and local improvements to the area.

And lower rates won't fix that.Prices going up help that a bit because then the premium to buy a new construction home and pre-existing home isn't as great. 

:)I'm strongly considering it at the moment, and I might end up starting on their service by the end of this week or early next week.

Still new here- I know I can find the cap rate by dividing the NOI by the market value but what's the most reliable way of finding the market value? 

With the exception of financials. 

I googled the address, and it comes up as a condo for down there, but why would a 952 number be the rental manager for an apartment in Miami? 

Im saving up for at least 20% down.
