we are joint freeholders with two others in house converted into three flats. we have the top floor and want to convert our loft. i offered to maintain roof as a thank you to other two flat owners but lawyer says that is not good as mortgage lenders to the other two will probably prefer joint maintenance. lawyer says we could instead offer to redo entire roof (as we'll already be doing half effectively) as a nice gesture. i'm scared about costs and wondering if there is another solution. does anyone have experience? would be very grateful...
