Ideally, someone who specializes in real estate.

Granted, you receive a 50% discount for booking 28 days or more which I did.

If you're doing 4 at once you might be able to get a discount or financing... and if you buy from big box store you can always buy discounted gift cards for a discount ..

Was there any special steps with regards to the original mortgage and the refi process?

@Eddie Quispe Commercial broker often specialize in asset classes.

@Josue Godoy This is a loaded question- If you are planning on being very specialized in a single area it would make sense to go one way or another...this is an oversimplification, but the point is to be diverse enough that you can process any type of deal...for example, really focus on an area you like well...like flipping, but learn how to hold properties as well, and whatever else you want to learn...as you grow, you'll be receiving many leads from different sources...and the point of this rationale is that you should have enough tools in your toolbelt to put your deals in a "best use" funnel...then profit on the other side.I'm only adopting this position because you are so young and have so much time in the industry to elect to pursue and specialize in one strategy.The simple answer is related to your goals...assuming you want passive income to replace your W2 means that you will need to buy and hold properties...similarly, if you start flipping properties, you're creating another job for yourself and creating a liability.

However, the particulars when the previous owner is in residence are usually a special set of circumstances. 

I noticed that investors have had a very hard time getting MH parks financed so I went and created relationships with several lenders who specialize in it.  

Every calculation model I see seems to discount that part of the transaction when it comes to cash flow.

What I am realizing is that discount points and closing costs itself is accounting to around 4-5k.
