From there you will narrow down your search, the bank will impose a price limit.

Also if you have a bank that will lend with a 30 year Am on a commercial property let me know....

This means keeping corporate records, following corporate law, having separate bank accounts, not co-mingingly funds/property, etc.

My first question is, how is the bank going to know that it's now an investment property?

Some banks won't accept it though.  

So if you're truly playing catch up on retirement, you have your precious capital in two buckets:a) equity in the house earning 4% onlyb) REI earning 10% +Then, it's the same argument on prepaying the mortgage ....you're sending a couple hundred dollars to the bank to avoid 4% interest.

If you need more help, I'd contact the local government entity in charge of titling mobile homes in your area and explain the situation.

I use Ally financial for my rental checking and rental reserve account, about the best interest rates you'll find for FDIC insured bank accounts.  

Sometimes a house is distressed to the point where banks won't lend so they can only work with cash buyers, throwing realtors in the mix just slows down progress on finding a qualified buyer.The market I invest in is pretty cool, so a house will sell for 60 or 70k, but it will be on the market for 6 months.  

They still have a mortgage on the property and the bank will try to protect their interest.
