Are they doing everything possible to expose properties to the broadest possible market?

Hi @Jorge Lopez appears the iOS version of the bigger pockets app has been pulled off the App Store, usually that happens because apps are not getting updated to meet current standards but I would have to defer to the BP team to clarify.

You do not need a separate LLC for each property or a series LLC!

What is the property appreciation in that market?

Patio door prices can depend on the Model of Patio door you are looking for, for a standard 60x80 in white it will cost $1900.00 colors can be added, and for a patio door 72x80 the cost will be $2100.00 Outswing for a 60x80 will cost $2600.00 installed, and for an outswing 72x80 it will cost $2700.00 installed outswing with Grills for a 60x80 costs $1860.00, and an outswing 72x80 will cost $2300.00 installed.You also add blinds to all sliding and outswing patio doors for an additional charge.
