The best place to start for this is to go out to your centers of influence and let them know about the investment opportunities that you have.

This can be influenced also by where you are buying.  

I have listened to around 15 books this year, many several times because the info is that good.The New psycho-cybernetics (by far the best)Think and Grow RichHow to Win Friends and Influence PeopleRichest Man in Babylon4 Laws to Financial ProsperityMillionaire MindGoals, by Brian TracyPurple CowThe DipE-myth4 hour work weekArt of the Sale, Zig ZiglarTotal Money Makeover7 habits of Highly Effective PeopleRich Dad Poor DadSecret sauce, Steve CookHow to talk to Real Estate Seller -Bill GuerraCrashproofI also listen to Peter Giardini's pod casts at blog talk radio, and his weekly market update at the clubmastermind.BTW, every book on this list I would recommend.

Perhaps you need to put more feelers out there and increase your sphere of influence.

My circle of influence may be able to help but they are hesitant.

None of this influenced my decision to purchase the property, but at least I'm cash flowing on day 1.When I met the tenant in unit 1, she was already asking me if she could break her lease which ends in May. 

I think the ins and outs of the loan are all heavily influenced by your particular 401k account rules, but if it is administered through one of the larger 401k administrators then it should be a relative breeze for you from what I understand.

I think there are a lot of factors into deciding what your best decision wil be with your properties, but generally speaking the market is very strong in Montclair right now and may be a big influence in what path you choose.

We've discussed this in other threads as well, opportunity costs and similar investments, risks, management expertise, efficiency, vacancy can all play in actual rates of return and be much different from one owner to another, not to mention market influences. :) 

I will however need to learn to systemize finding buyers beyond my spirit of influence as that will run dry from only living in GA for 2 years.It's going to be fun talking to the brokers and finding the shoe that fits best.
