The difference in value can be substantial but the only real way to know is to simultaneously list a property as a combined sale and as separate sales and be careful about what offers are accepted as its the last chance to choose one method.

I have already started practicing analyzing properties and in the process of investing in a Duplex to utilize the House Hacking Strategy.

In any case my tone is not conveyed well through writing this, I’m not advocating that this is a good practice.

I would not be doing a simultaneous exchange.Any information on this would be greatly appreciated.

My ultimate aspiration is to use the funds I make from practicing to invest in real estate and achieve financial freedom and thus practice pro bono for people in need.

Out of curiosity, what kind of law do you practice?

Practice analyzing properties that are on the market even if do not intend to use the MLS for your purchase that way you are comfortable analyzing properties and the more times you do the better you get at it.

So in practicality i do not think those companies are a great option.

Some people might think that's a conflict of interest.All in all you might want to talk with a good real estate attorney who practices in the county where the property is and make sure you understand the risks. 

Yes you can do it, you just need to make sure that you dont break any licensing laws or you can get fined for practicing real estate sales without a license.
