If I can afford it, would it make more sense to empty the whole complex and bring them all up to what I want them to be?

The houses are much more affordable.

When you consider the cost/return of this, I think it’s likely that option 2 gives you the best return. if you’re targeting low/middle tenants, many couldn’t afford to purchase their own appliances.

There is a lot of asbestos siding in Florida and it poses no danger/health concern unless it is "bothered." 

So I am just wondering what some ideas are that people use for affordable, reliable and repeatable designs in kitchens and bathrooms. 

One members reasoning being she didn't think we could afford it.

If you keep the property from health and safety violations, manage like a business, and carry good insurance you are best off vesting in a single entity Revocable Living Trust- this gives you stand alone one property protection and saves a boat load of money.

we are buying higher quality now that we can afford to do so and they are MUCH easier to manage but I do think our experience running low income properties has made us better landlords. 

Many of these systems require scales of efficiency small DIY landlords can't afford, especially for Class B & C properties/tenants.Biggest issue you want to investigate if their "boots on the ground" for inspections, maintenance and showings.

As a consequence, competition for affordable homes under 350k is fierce, much different to the market over 700k which is still only "warm".
