Another important point for Engineered Certification & Foundations For Manufactured HomesAdding a retrofit doesn't mean the existing components are removed (above).

How old are the various components on the house, what are their remaining functional life span, and figure out the costs for them.

I want you to really internalize this what I am about to say.  

They are one of the main components in the changes we see in the housing industry, and will continue to be for years to come.

@Drew McLaren  there is some exponential component on larger loans as you state howeverhere is how I looked at it over the 30 years of loaning hard money.IF your in a foreclosure situation.. the value of your collateral is generally not what it was when you started the loan..

My wife and I use these properties for our personal businesses.I'm not a licensed contractor but I do have my Residential and International Code books.

Flipping PropertiesIf the primary objective of your real estate business, or one of your real estate businesses, is to buy, potentially fix up an existing property and resell it within one year, the Internal Revenue Service can consider that to be an active trade or business.

For good cash flow... look for bigger deals, with a value add component, in which you can afford to use on-site property management (at least 75 units)...

In full disclosure my business partner is the President of the REIA and I am an active component in it as well, but it is a great place to network and learn new strategies and skill.
