Older area home issues

[Robert Mendenhall]

Good morning BP,

Ive been digging in and looking for a multifamily in Columbus to start my REI journey. I was wondering about some issues to look out for in older home areas. A lot of the homes were built around 1900. I was wondering if anybody had some area specific issues to keep an eye for and what are the BIG problems to avoid. Such as settling or certain areas that flood often.
