How come none of the brokers found the best deal for me and how could I help other people get the best rate for a mortgage.

I have a pre-approval through First United Bank for mortgage no less than $40,000, and for anything under $40,000 I work with Oklahoma Credit Union.

My tenants are still paying down my mortgages.

If you buy at 373k, you're probably paying around 2,200 a month in mortgage.

Read books, take online courses, and join local real estate investment groups.

There are rules in Ohio where if the borrower has more than 20% equity or has held the land contract for more than five years then the lender must go through a judicial foreclosure as if it was a mortgage. 

The online realtor sites give you dates but they are usually in the past and always have a disclaimer that " Auction time and dates can change".

You're just supposed to re-purpose your rent payment into a mortgage payment. 

Now it’s more than $107,000, according to the NAR.when rates were at 8% this was publishedA mortgage rate that stays around 8% means median home prices need to fall by 35%, to $265,000.If rates stay at 8% and prices at current levels, income needs to increase by 63%.

I would not recommend any online courses like the above reply suggested.
