We own two rentals in a small town in Indiana.

Myself, Father, and Brother in law want to to begin buying rental properties and possibly a few fix and flips. 

I have a condo as a rental with minimal loan balance in San Diego. 

New to all of this, need to insure home for rental.

Looking to see what others do to market their own rentals/properties.

While opinions may vary, I rely on data to help drive real estate decisions and planning.Key ConsiderationsEducational Attainment: 77008 boasts higher numbers of residents with bachelor's (12,241) and master's degrees (5,739) compared to 77063.Demographics: 77063 has a higher percentage of foreign-born residents (41.02%) which typically indicates a strong rental market and with 76.86% renter-occupied versus 32.60% in 77008.Economic Factors: Median income in 77008 is $140,609 with a low unemployment rate of 3.37%, whereas 77063 shows lower median income ($51,899), higher unemployment (9.99%), and more families below the poverty level (16.51%), which may indicate economic diversity but also potential rental payment risks​​.Age Distribution: 77008 has more middle-aged residents (35-54) [8970 compared to 6,115] and a slightly higher proportion of young adults (25-34) compared to 77063 but both are popular with younger adults suggesting strong rental markets equally exist.

I’m interested in investing in more real estate to have long term and short term rentals for passive income.

With this T12 I am suspecting the apartment wasn't fully occupied in the preceeding 12 months, hence the low rental income.I am very concerned with over 40% operating expense.

., long-term and short-term rentals, notes, BRRRs, etc.), or did you mean diversify types of notes (e.g., performing, non-performing, CFD's, short-term, long-term, etc.)? 

With gratitude, Juliette  @Juliette Olsen we do manage long term rental properties in Orlando and there are plenty of great companies here, but obviously not all of them out there are great, so it might take a little work finding them.
