I add $400 for permit, and $500 for Engineer's report.

Permitted and properly installed mfg housing on land is treated the same as stick built, I've not encounter lender limitations on such housing.

@John Hill,Perhaps a better question would be whether your local ordinances, etc. permit such a building.

And only on their approval, after submitting the proper permits and applications and showing them what the work will specifically entail, and once approved may I then commence with the work.  

Unless permits and the addition are brutally simple, which in this day and age I doubt it...

Our gut instinct is to put the tenant relocation upon the seller as part of a purchase and sale agreement in a manner that is allowed under both Federal and local regulations and incorporate that time period into our development activities--i.e. budget and development planning and preliminary approval of financing by our portfolio lender--we would probably hold off on architectural and permit work until seller and tenant have come to an agreement for tenants re-location and hopefully close on the property after the tenant has actually vacated the unit.

I will keep in touch, here is the facebook currently getting permits and what not - quit his job at Amazon to follow his passion!

We weren't planning on buying another one until the middle of 2012 (we are old school, buy & hold with traditional financing investors), however we may be interested if the price is right.Do you have permits for the back rental?

I am curious about experiences dealing with the permitting process in particular, and TRUE final cost comparisons, relating to these types of homes.Thanks for reading...

They would have to re-build up to code if the work required permits.
