Really it comes down to each individual deal, and you have to evaluate very deal yourself. 

The individual who wants to be paid for their work, they should be paid for the actual project not hourly.

I'm individual but there are companies who do the same thing.

Im still going through my 90 hour online class to get my real estate license.

Your individual situation has to be evaluated. 

Listing, applications/screening, leases, online rent collection, and maintenance tracking? 

Reading online reviews of Shaw, LifeProof, and Stainmaster all seem decent quality.

For example, if you're LLCing it - which may make sense for a partnership - that'll make it more difficult to get a conventional mortgage.Like anything in real estate, if you're going to be including or working with another individual, you'll want to sit down with a good lawyer and put contracts together that protect both parties in the event that something goes awry.

I found a template online for excel that I use to record my income and expenses and it has a section to track mileage and multiplies your mileage by whatever the allowable rate is for business travel ($0.535 cents last year).

I read online that they primarily look at DSCR and operating income.
