Are you including the signature "enclosed porch" feature that a lot of the small mutli-units have here in DC? 

@Michael Weveryou can use self-directed Solo 401k loan feature which would allow you to borrow against your retirement account for up to $50,000 tax free and penalties free.

Try the search feature.

(FYI, expense reimbursements from tenants is a common feature of commercial leases.

It was recently featured as one of the top 20 cities for real estate investors.

I guess my question is, will updated and more modern features be worth the initial and eventual price of instal and repair compared to the price of rent??

Make sure to ask questions, and utilize all the features of the forum.If you can setup a meet in the afternoon on the weekend, I'd be willing to join. 

Are the old features fairly standard for that area to where you can get the $1000 a month without replacing them?  

Yep, check with your state.In Ohio, you have to be licensed, with a broker, and be a REALTOR to get access to our MLS (plus pay all the dues).If you're just getting your license to get access to the MLS then you're better off creating rapport with a good agent you trust and asking them to set you up on their auto-notification with the criteria of houses you're looking for (On our MLS system, we have that feature to setup clients on auto-notification, so as soon as a house comes on the market that meets their criteria they'll get notified).Also, if you get to know an agent(s), they may know of houses not on the MLS that will be coming on the market, so you could have first access to it.

Bummer, this would be a great feature.
