The best part about real estate is the creative aspect of putting deals together.

Normally I'd say that you should just throw all his crap out but I think you brushed over the most important aspect of your deal.

To really grasp this you'll want to understand this key aspect of real estate:  A single family home is one product and multi-family (5 units or more) is a totally different product.   

To gain a little capital I am interested in the Rehab and flip aspect of REI.

Buying and selling heavily depends on the management aspects knowing the market rents and maintenance costs.

Which aspect to consider?

The rent collection aspect is just one part; might want to keep in mind a platform that was built for smaller DIY landlords (1-15 units) that offers all of the necessary tools; ie. listing to 10+ major listing sites, comprehensive tenant screening, state-specific digital leases (based on the property address; uses that property address to import all necessary local clauses into that residential lease and allows you to add custom clauses and renter rules to it as well) AND online rent collection. 

I'm sorry if this is the incorrect place for a post like this (I thought it would be since it's a question about an aspect of the podcast), but I had a question about the music behind one of the ad read's that Brandon does on the BiggerPocket's podcast.

The BRRR method would've been incredibly helpful to know about before my first deal.2) Understanding how to correctly manage a property.This aspect is very underrated IMO.

Don’t spend all your time on the peripheral aspects of your business. 95% of your thoughts and actions right now need to be about marketing.
