I just learned this has now become a voluntary requirement for the time being as there is a court order to stop this reporting.

I'll be bouncing back and forth between the two cities over the next four months before I move in order to get life set up and trying to learn the city... and hopefully find my next project. 

I have not thought of using DTI instead of 3x the monthly rental amount in order to qualify an applicants income, but you made a great point regarding the priority that tenants might give a car payment.

This would likely take coordination with a tenant at some point - (ie - plenty of notice to them that they must vacate in order for you to sell the property)Since your current home is free and clear -  you could do a cash out refi or take out a new mortgage on the new house to be able to buy your paren't house and pay off the mortgage.  

Net Sale - Is the contract price, minus the closing costs and commissions.adjust cost basis - net sale = net gainYour gain is made up of profit and depreciation recapture.

I know they are compensated per unit for the inspection, do you think it would be an issue if I just registered a fifth unit and made sure it met all the requirements?

Quote from @Sherry McQuage: Make sure to check the zoning to make sure mobile homes are permitted there; check for any hazardous waste designation for the area; will you need to have the parcels surveyed out in order to sell the size you intend? 

When all the dust settles, and the  person searching is tired and discouraged and gives up, Jerry may not have bought  a single lot, but he's made some money from the training he sold you, which was his main goal from the beginning!

In order to work Joes program would take at least 5-10k.

At the very least, I would request a refund of the original application fee as the City made a mistake causing you to have to submit again.
