We have a Chicago general contracting business, and handling the field operations is a ridiculously heavy lift.As far as finding customers I think you'll have some good success with gorillia marking at some of the local investor meetups. 

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.

I'm now considering expanding my real estate ventures into building custom homes, but I know this is an entirely different beast between the required capital, learning curve, time committment, etc. 

I'm a Project Manager at an Architectural Firm specializing in Custom High-End Homes. 

Do you check Landlord references?

Quote from @Ogonna Odo:  Small ones will not, they typically like cash or checks.

I recommend two accounts: checking and savings.

They’re requesting what feels like an unreasonable amount of information, and the demands keep escalating.So far, they’ve asked for:A video tour of my home officeCredit checks on me and my partnerCopies of the deeds for every property we ownA copy of my partner’s home lease and utility billsBusiness phone billsA signed letter from the bank verifying our accountsBank statementsHonestly, it feels more like qualifying for a loan than trying to become a customer.

Yelp is a good source because it lets you read reviews of actual customers.

The Automations are very good and you can customize mass follow-ups 2.
