The listing agent showed it several times but a month went by and he didn’t process the listing paperwork so I instructed my agent to draw up an offer over the list price he told me when he showed the property to me and submit it.

I have thought of investing in Manufactured home / Mobile homes for the STVR, have you looked into that instead of using the duplex's?

For example, my market in Huntsville is fueled by Redstone Arsenal and manufacturers in the area.

Look for cities where there is a good mix of manufacturing, warehousing and overall good job market with low unemployment.Hope this helps!

Therefore, it is incumbent upon us as investors to insure that our contractors (including title companies) follow our instructions.

Also, you can look up the title on new homes being sold to figure out the address of the location where manufactured homes come from including the manufacturer information.

We are looking to purchase a property with a second placement manufactured house on it, we would also use it as our primary residence and have been looking at options for financing, (we do not qualify for VA), we would rent the RV pad and possibly the pasture for part of the year so it does have some potential rental income.I'm thinking about making an offer with seller financing.

Actually, there is a sub sub group of investors who do deal with mobile home park manufactured homes.  

I am also hearing about Intel investing $20B to build two chip manufacturing plants in Ohio.I see many small multi-units under $200k, and market rents are generally between $900 to $1500 for 1 to 3 bedrooms in C-grade neighborhoods that are next to B/C+ neighborhoods.But, don't trust my words. :)  If you decide to visit the city, maybe we can get together for a coffee meet!

You always get what you pay for in construction materials so I'd recommend avoiding home depot materials, bargain retailers etc... and paying a little bit more for a name brand manufacturer of this product with a good track record for quality.Think about possibly a 1/3 staggered joint instead of the 1/2 staggered joint, it looks a bit better with this product.
