For details: One example property is a SFH, south west of Little Rock (close to 430 and 30 intersection), price is 230.

I see many situations where one generation wants to buy out a prior generation or, more typically, siblings.

Typically, it’s reasonable to deduct for things like deep cleaning if the place was left pretty dirty.

True, but (a) they were typically experienced investors, and (b) today's market includes record prices and high mortgage rates, which is a double whammy. 

For example, this investor that I met recently said not to buy properties at tax auction for 100+ different reasons.

Hiring a STR professional typically pays for itself and allows you your time back.

These typically include services like renters insurance, HVAC filter delivery, pest control, and sometimes utility management.

@Sakib KhanRecommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a property in Class D area to Class A standards, what quality of tenant will you get?

In that case, you’d typically need to file a legal challenge, which could involve going to court and showing that the restriction is unnecessary or unreasonable.The best advice I can give would be to consult a real estate attorney to understand your specific situation and options.

I mean by safest is on the volatility, for example STRs have many different factors, seasons of the year, local government regs and much more.
