For that reason, credit worthiness may not weigh heavily in your screening process.  

Your buy formula is a personal choice as far as target yield.Due diligence in broad terms covers:1) marketability of note, legal, etc. documentation2) the borrower (credit worthiness, payment history)3) the collateral (equity, other liens etc.)If you are proficient with a financial calculator make sure your settings are correct for # of payments per year.to calculate "i"/yrenter "n" number of remaining paymentsPV= the price you pay for the note if its $50,000 enter - 50,000PMT= scheduled monthly payment if it's $500 enter +500FV= usually "0" if it is fully amortized (if there is a balloon enter that number +)Most people get tripped up on when to use a negative or positive number.then press "i/yr" that will be your annual expected yield

@Justin YoungDeposit accounts balances, years in business, sales and the credit worthiness of the business are factored into the decision of the bank in addition to collateral which is the #1 reason.  

I received more than one phone call from companies claiming to offer a service that helps people establish an LLC, obtain a business credit card, and help build their client's business credit worthiness by making purchases on said business credit card on behalf of the client without providing advance notice to the client!

Have your credit score be as high as you possible can get it, to prove your creditworthiness to lenders.Talk to a local lender to see what sort of loan you could qualify for.

Those car loans only care about income and credit worthiness.

Your acquisition cost is typically less, but a mobile is typically not as nice or as comfy as a stick-built, which will likely yield lower rents and sometimes a less credit-worthy or lower performing renter.  

A potential borrower's ability to do so is taken into consideration by lenders all the time (in addition to all the various "hard" factors that they take into account - whether the numbers make sense, creditworthiness of the borrower, etc.)

The issues:  Need collateral, credit worthiness. 

And,  of course,  review your criteria insofar as creditworthiness,  rental history,  etc.You also don't have to offer a payment plan if the total of move in costs is less than 1/4 months rent,  I think.
