Do they charge any higher or lower?

The primary reason is that my parents' risk tolerance is much lower than my own (they are retired and are on fixed income).

Rental income would be $12-14k per year, so your netting $1500-3500 the first year before lowering the interest cost over time and increased rent (rising at 8% per year).So for $0 out of pocket you get another unit, equity growth(over time), income that grows and you created a unit of housing that didn't exist before.

Reduced Market Visibility: Fewer potential buyers, possibly leading to lower offers.

Quote from @Patricia Via: Why lower your standards or add risk by accepting tenants with quirky history?

You can win most tax appeals when your taxes are just out of whack for comparable properties so if you can find examples of similar properties with lower taxes, that is the only way you will win.

Which do you think will have lower maintenance/cap ex?  

@Celso Rodriguez BRRRR works great in markets where you can buy homes around $200,000 or lower.

This is a new underwriting guideline of the insurance companies because they haven’t been profitable and must raise the rates and lower the risk factors in order to comply with state regulations on adequate reserves and future solvency.  

The lower property prices mean you could buy multiple properties, potentially doubling your cash flow.
