Finding a contractor who follows through and does good work at a reasonable price has been my biggest challenge over the years. 

The fact that you're consuming content and asking for advice shows you're committed to doing it right, which is the most important mindset.Here are some thoughts based on your goals and challenges:1.

. - Biggest efficiency savings is from last minute reschedules, prospects running late & no-shows.- Security is the big challenge to avoid theft, vandalism, squatters and scams.- Security options include ID verification, geo-fencing of prospect cell phones and video call verification.

Ignore him as he knows nothing of Sacramento RE.Here is a challenge for @Luka Milicevic.  

Seasonality will be your biggest challenge.

Verifying last 2-years of rental history and income/employment extremely important to find the “best of the worst”.Tenant Default: 20-30% probability of eviction or early lease termination.Section 8: Class D rents meet program requirements, often challenges to pass Section 8 inspection.Vacancies: 20%+, depending on market conditions and tenant screening.Cashflow vs Appreciation: Typically, all cashflow with little, maybe even negative, relative rent & value appreciation.Where did we get our FICO credit score information from?

I'm ignoring any and all appreciation in my analysis (natural or forced).The biggest challenge I'm noticing is my entry point and available cash on hand.

Also, these are not easy portfolios to sustain over time due to the upkeep and maintenance challenges.

I’ve worked with a lot of out-of-state investors, and the biggest thing I see is that success comes down to your local team and knowing the neighborhoods.
