They do draw a hard line with cloth wiring, even if it is in good condition and not knob n' tube. 

I am fortunate that I do not owe on my duplex but we’ve handled selected two tenants that fit with our lifestyle and therefore have the other side rented at under market value.

Another route would be a home equity loan, which functions like a second mortgage, providing you with a lump sum at a fixed rate and payments.Each option depends on your goals and the terms offered, so it's important to evaluate which fits your situation best.

Originally I was also hoping to find a package that would do more of the property management basics for me, like running ads, screening tenants, collecting rent, collecting e-signatures, etc.What I found after months of looking is that there is no one-size-fits-all platform out there.

I have Benn investing in Real Estate for 30 years and consult with all the clients that I work with about the property and strategy that best fits their investing goals.  

Either way buying it and having on site will save you time and labor costs provided it fits the space and works with the existing drain. 

Also have your realtor set you up, so you automatically get an email any time a listing comes up that fits your criteria...and check MLS regularly.Look to see who the listing agents are as some specialize in condos (or certain buildings) and they may be able to let you know when they are going to list a place and you can be the first one in. 

$125,000 to $180,000 per door depending on size and what will fit.

I would argue that you are better off having a smaller place in Orlando that fits a family under 6 people. 

If you don't have enough to buy with cash and will get a mortgage, I would focus on finding a good-value home with a solid CAP rate and Cash-on-Cash return that will appreciate and fit the most common rental size house in your area.
