My partner and I have a General Construction company (CSL).

Personally I will not work with them specifically due to this fee.

I also have a background in software, having founded and sold the majority of my software company in 2014.

I sold my company two years ago and I'm looking for investment opportunities in the real estate space, specifically single-family houses.

Quote from @Dereck Olson: Hi Nicholas,  Just a thought from the possible tenant's perspective, but filling out a prequalification form and/or providing personal information before they have even seen a place and know if they will be interested in living in the property might be a bit too much to ask. 

@Corey Pinch if you're a go-getter, make sure you find a company, or negotiate, that you're directly rewarded for your hustle - commissions, bonuses, etc.

But you'll have to either manage it yourself and develop a really good skill set in that or get a smaller company that doesn't have too many properties to manage who has a high skill set management for you, but then you need to pay for that.

I typically don't comment on other's businesses unless I know from personal experience.

You can try Rhino or Qira, but these are ventured back companies. 

They tend to have less experience, less knowledge, fewer resources, and are more likely to be crooked than a large company that's been around for 30 years.
