Let's say you rent the cheapest unit and can collect about $2250 per month for the other two units. 

I've also set up an automated toll free number that collects their information when they call in that goes into the software which has been super helpful.1.

Just layout the requirements for renting and put that in your ad.If you go this route just make sure that you have a good reserve fund and be aware that you probably will have a couple months each year where you collect no money because of a tenant changeover etc.

I currently use them for rent collection but have not used the screening feature.   

I'm looking for some collective wisdom to chime in with their own experience on this.

TLDR: Lesson Learned: If you are buying a property to house hack and the unit you intend to move into is occupied with tenants and collecting rent after closing, then for tax purposes, it will be considered a short term rental.

I would absolutely look to turbotenant.com, hemlane.com or cozy.co they each offer similar services, but marketing, online rent collections, credit/background checks, maintenance work orders etc.

Will the payment on that mortgage you'll be carrying be better than the rent you are currently collecting?

I just want to show proof that the house is indeed part of the LLc and the rent that's collected is going towards the LLC.
