Hey Anthony,There are many ways of valuating a property and Nick has asked many important questions.

The first 5-7 years are the most important!! 

This is why it's very important to find a really good tax accountant specializing in real estate.

I have considered for several years the importance of general investing, but recently have become increasingly interested in real estate investing.

this is a common theme of course on BP its pretty much every day.and you pretty much have all those that live in a market target a market .I like @James Wise cut and paste responses he does .. he nails it well and its worth cut and pasting every time someone ask the same question that has been asked 1000 times.I like to Add James that when going out of market.. also if you simply buy at the median price points of any given MSA your buying in an area were you have a lot of homeowners buying generally... so you get a mix of cash flow and appreciation and or more important you have a defined exit IE you can sell to a homeowner as opposed to buy at the bottom of the price point and the only out is to an investor..And Frankly your company is kind of a unicorn in the US.. there are not many companies like yours that specialize in reselling these assets for individual owner/investors. 

I'll register and everything when the property is "officially mine" and the other more important details are filed and put away.     

Get quickbooks set up, it auto imports your transactions.

But then you would be signing a new Mortgage stating you intend to occupy for another 12 months.If you were using the right loan officer from the start, they would have helped you structure better and use a Conventional Home Possible to buy your 2-unit, then you would still have your FHA available for the next property.In your case, you would need to refi to an investment property loan which is a max 75% LTV in order to buy a new primary right away using FHA.This is why it's so important to pick the right lender, because now you're stuck. 

This will become more important with numerous LLCs.I know this is a question for a CPA and/or lawyer, but figured that others are likely wondering too.

You are asking an important question.I recommend sitting down with your husband and writing down your goals.
