Third example of why single family is so different from commercial is because you could buy a single family next week, get a thirty year loan and the only time you interact with the lender is at or before the closing table.

Reliable sponsors will often be willing to provide a schedule or table with this information and should openly detail their past successes or shortcomings.

So if your property is in a solid neighborhood you should be fine or affected slightly as compared to French neighborhoods which will basically be put on pause for that time

Talk to a lender and see what your income qualifies you for and how much cash you need to bring to the table.

If they truly don't have any of the necessary cash to bring to the closing table, I'm not sure what you can realistically do because that's a pretty big difference to make up and it sounds like it'd need to go through the shortsale process.But can they come up with some of it?  

They do cost, but they tend to demand higher rents and have the will to hold out for them (I caved a few times and left a lot of money on the table).

Yes My unit is NOT in the french quarter so 2618 would be very high for it.

If it's not producing great returns and you've got a solid offer on the table I'd definitely consider it.
