My investment goals include building a portfolio of rental properties, focusing on both single-family homes and multi-family units.

I understand there is also property management software that combines ACH payment capabilities with feature with basic book keeping features, perhaps work orders/repair requests, document(lease) archives, leasing/listing features? 

Do you own any properties yet?

Yes, they made me the property manager.

I currently have a property with a 4 unit on it.

Also as a sidenote I assume you are lending on non owner occupied homes - never lend on an owner occupied property.

We've bought over half of our properties during the holidays.

By investing out-of-state, you can find properties with lower prices and higher rental yields.

Ive started a mail campaign with properties in my local area( Providence County).

The ones who haven't heard about it seem to not care much or are grateful to be informed of the "changes".We are getting less objections when presenting the exclusive agreement than we were prior to 8/17.
