There's other dialers out there that's more custom tailored to organizing calls, lead follow-up plus much more cost effective and honest with a live customer service line.

Hi Jeff, as everyone has mentioned, I would suggest house-hacking a 2-4 unit if you have the means.

@Hamidou Keita I would recommend if duplexes are limited if you can get a 4-5 bedroom house and either rent by room for house hack or splitting a big house into 2 and adding a kitchenette and separate entrance as a more cost effective ROI option 

Since you’re committed to staying close to family, I’d suggest focusing on properties that might need a little work but have potential for appreciation in your market.
