I found it ironic and I sat there with my back aching in dirty clothes from a long day at the crazy house.  

We also bought their 3 yr old appliances, patio furniture & newer BBQ for $950.

If a house is from 1900, pipes have probably been replaced at least once already, but it's very likely that you'll have old, rotting cast iron drain pipes, corroded copper water lines, and sometimes even gas lines that are done unsafely.

Elisha,If your baseboard heaters are not the old cast iron type, then replacing them is not a big deal – you can replace the outer steel enclosure, or the heating element, or the entire unit.

I found the old cast iron waste pipes & the antiquated traps they used were significantly blocked/corroded. 

We know how to ride the tax-free compounding interest wave while investing in what we know:-)  Ironically enough, I too work in the Memphis market with MemphisInvest.  

Someone that just wants a yard for a pet, kids, or bbq may be more common.I am not sure how a renter would hurt themselves with a compost pile, but I would get a batch finished and time that with your renting if it is a concern.

for 15k a door. .he was giddy of what a great deal he got... spent about 10k a door getting the units back to rent able condition putting in a new hoop and BBQ area.. well within first 30 days hoop is destroyed BBQ are stolen he had one murder and a bunch of other violent crime he thought we would sell at a 15 cap and make about 500k on the deal.. he ended up selling and losing 400k... all in 18 months place ended up boarded again.. these areas are only appropriate for those that FUlly understand the market the tenant and how to run these areas.. an investor buying a SFR if its in the wrong area will just throw their money away.. you need to buy quality.. if you do you can a good day.. although be aware values do not rise there. 

Ironically I was just going to post a question wondering the same things thanks everyone for your great answers.    

Expect it with college kids, I don't tell them they can't I tell them or convey to them what is expected, maturity, responsibility, acceptable behavior, disturbances and trash left over from the BBQ.
