I'd like to work toward setting myself up to purchase another property next summer.  

Setting Appointments.  

Facebook, Craigslist, door knocking, direct mail, cold calling, are a few ways to market.Also, to answer your question "Generally how many times do you market postcards to the same list?"

Currently hold no assets.4) Holding 300K in professional school student loan debt at 6.8%, plan to refinance perhaps at 5%I'm trying to figure out my strategy for avoiding taxes on my high salary/income that will start soon, and hoping to invest aggressively in the next few years in order to set myself up for passive income in the future.

If you bought the previous property in your own name, you may need to acquire the replacement property in your own name - however, as Dave described, you may be able to set up a single-member LLC - consult your attorney on this one.   

I am investing in other real estate but have money set aside for that.

@Abdul Azeez, I think that the problem is that you are stacking the deck against yourself trying to do all of these things on your first deal:1) Purchasing the property from an online auction site / bank, which is notoriously tricky even for the experienced investor, due to their proprietary contracts and minimal due diligence period and strict deadlines.2) Working with a new contractor that you haven't used before, or seen their work before, and who may not be used to dealing with investors.3) Trying to get conventional financing on a property that has a short closing time and where the mechanical systems cannot be tested.4) Working on your first deal by yourself instead of partnering with a local investor who can guide you along, or at least a mentor who you can turn to with questions.My advice is to make it easier on yourself by considering buying a property with a standard contract and longer due diligence period, network with local investors who can provide you contractor contacts and also some guidance, and consider using private financing or hard money instead of bank financing.In my opinion, buying from the online auction sites is a more advanced strategy that you can use once you are able to ballpark construction costs yourself and/or you have a trusted contractor you've worked with before and/or you have private financing or hard money set up so you can close fast and/or you can purchase the property without interior access and hope to get lucky in terms of condition (but still buy at a price where you are comfortable doing a full rehab if necessary without losing much money) and/or you are familiar with agreement of sale contracts and closings in your state so you can assess the risks of using the bank's seller-friendly contract.You're already doing the right things by asking questions on this forum, and taking action.  

Make sure any future investment properties that you are selling and intend to use the proceeds to purchase other investment property, you set the exchange up well before the closing on the sale of your investment property.

I am set on the existing red going to sage green to match the existing house.  

Once you're ready, make sure you take action and set some goals.
