To build up the value of your home my mother had a real estate agen to tel her that she had to much shrubbery in front of hte house but to maybe add some thru the yard . Also haing things trimmed out helps to bring it up as well and the types of plants and trees you have on your property makes a big difference. Picking and choosing the right kind've plants is very important . Yes a small pond will as long as it is maintained. so thats my best advice!
