I am trying to sell a manufactured home my wife has owned for roughly 13 years. 

If it's a long term buy and hold it's not a huge deal as long as it produces enough cash flow to be worth it.I would pay a couple hundred dollars for a structural engineering report and take a reputable mason to evaluate it as well. 

due to drug manufacture. this may be a deal breaker for my wife.

Get a quote from a reputable contractor if you don’t have enough experience to ballpark it.

I am still living in the past, where your word is your reputation and your reputation is your character.

I recently booked a single family home from a reputed builder in Frisco, Texas.

My end goal is to become and active and reputable Real Estate Investor.Areas of Interest: Dallas/Arlington/Fort Worth-Wholesale/Agency (I understand there may be conflicts of interest if not handled properly)-Flip/Rehab-Buy & HoldDoes anyone have any suggestions?

While there are some shady characters out there, just like in every industry, there are a handful of very reputable ones.

Looking for advice on how to...if possible...tap into the equity of a manufactured home I own as an investment property. 

I work with some projects on container homes with a container manufacturing company in Vietnam and the price is around 10k-15k for finished one (include plumbing, electric, flooring etc.).
