Currently, I own my primary home and a rental in San Antonio, TX. 

I've been informed that completing the course alone may not be sufficient to pass the exam, so I’m seeking advice on how to prepare effectively once I complete it.Currently, my only other resources include a YouTube video, five practice exams, and a textbook.If you have any additional suggestions—whether online or in-person, paid or free—that could help me effectively prepare for the exam, I would greatly appreciate them.

I've seen some as low as 6k and as much as 14k annually.

I've closed a bunch of loans with Kiavi, Roc, and a few with ABL, I also closed with RCN, Easy Street, Lima One, and some smaller private lenders.I've come to the conclusion that the experience at the lender is not globally good or globally bad. 

So far besides a few books and a burning desire I am a complete novice to this.

I guess be happy it’s only a couple months and a cheap lesson learned?

With $50K and a DSCR loan, your budget will likely cap at properties in the $150K-$170K range, depending on the closing costs and any repairs needed.

No problem, I had cash from a refi, a HELOC, and a personal LOC.

People don’t want to share their quiet neighborhoods with renters who don’t value peace and quiet and a sense of community.  

I believe these systems only work if you have good employees, in which case a bonus is unnecessary.I provide strong compensation, some benefits like 401k, growth opportunities, and a strong work culture.
