I know the standard rate for rentals is 10%, but I'm willing to pay more, since trailers are by nature harder to deal with than regular houses.

All damaged framing can be left in place and incorporated into new construction. 

For instance, qualifying for the mortgage on this house used 75% of the rents on the double by nature of the leases we had on it, but they are in MY name, not the business.

Naturally, it depends on the temps.

A few being, 1)open stairways to main living spaces and the out side  2) window wells that allow natural light 3) amenities such as a bathroom Please share your thoughts on the effects on resale value and your valuation method for calculating these effects.Thank youPatrick

I will be sure to incorporate. 

Naturally this makes sense for a long term Primary Residence; however, also according to my calculations, these properties would have a hard time renting for $2400 (conservative breakeven w/property mgmt) if I up and moved somewhere else.

The challenge here naturally is how do you manage the property from a maintenance and leasing standpoint.

For the back fence I would consider replacing with a taller, wooden privacy fence (matching the adjacent neighbors) and possibly extending it forward along the sides of the house to make better use of the side yards by incorporating them into the back yard.

(that you sign at the same time), and then incorporated into the closing once you get the real legal loan docs drawn up.
