You need to become an expert at properly analyzing deals and assembling a pro forma package to present to investors.

Now, when it comes to building a house then you may have more control over each stage of development, which should allow an Investor to control costs and increase profits if planned and managed properly.

I do things the proper way. 

What kinds of trouble would I run into trying to purchase a home without the proper documents?

Then properly diagnose?

I always like to add a first right of refusal clause in there, so if the note holder/property owner wants to sell the mortgage at a discount in the future, they must first offer the discounted price to you to pay off in full.From there, you'll want to close with a title company as normal, getting all of the proper insurance, etc assuming its marketable through a warranty deed. 

The variation in price is a function of their business model: where are they securing their inventory and at what cost, what are their labor, marketing, and other business costs, and what profit they desire.To your specific question, "yes," the bank can basically offer whatever number they want.

Proper lighting and video cameras are the base layer.

Recently purchased an old but functional duplex which we will rent to some long term tenants.

The potential pain in the *** is you can't properly file your individual returns until you get your k-1.
