I have been studying real estate investing across many exit strategies including rentals, wholesaling and flipping.

I'm going to start studying up on various areas in FL next, but if you see an area that seems good, I'm all ears. 

I had about 20 rental doors in 1 1/2 years and this is all while maintaining a full-time job.My approach was basically buy, fix up, raise rents, keep for a couple of years and sell which I did with many of my rental units.

Print it off, study it, highlight it, and keep it handy for reference.At the bare minimum, you should know:How to determine market rent for your unitsHow to set rental criteriaHow to screen applicationsState law regarding due dates, late fees, and the eviction processHow to handle late rent professionallyHow to evict a tenant for non-paymentHow to get rid of a problem tenantYou could easily read those two books, study your state law, and then develop WRITTEN procedures for handling these issues within a month.

Well done Bryan - especially being patient and studying methodologies.

The purpose of this inspection:If the tenant wants to renew, I inspect to verify they're maintaining the rental and that I want to keep them.

Most of it is for multifamily apartments but these ratings flow into single family rentals too.A class = 0-10 years old, luxury apartment class, full amenities, great neighborhood, schools, etc.B class = 11-25 years old, several amenities, well maintained, good neighborhood and schools. 

The larger downpayments and high credit helped me set comfortable rent rates and maintain a cash flow. 

A quick search informed me that an MA LLC costs $125 per year to maintain. 

I have a feeling this study is an attempt to fill in data for small multi family and single family numbers which are simply not published.
