As an agent I often times refer to emotional appeal as a large factor on what drives purchase price. 

There are some HOA's that are in such bad shape they wont allow any type of loans and it must be a cash purchase.

I was to purchase a house in NC, but due to some information that was not disclosed about the house, we decided not to buy it.I will be getting my due diligence  money back and asked for money back for inspections but seller refused.  

I'd have suggested a down payment assistance program for your first purchase.

Seasoning for ownership typically starts on the purchase date.

And I don't think anyone else will be able to get a loan if you decide to sell it in the future - which obviously impacts its value.Yes, you can do Conventional, FHA, VA, and USDA loans to purchase existing or new manufactured homes. 

If the condo association allows for short-term rentals, it most likely is not going to be HUD approved, which will mean each unit has to be purchased in cash or using a Non-QM loan.

I've included an example below to help illustrate this.So different lenders have different rates (which do vary even for DSCR loans) but these are factors they all consider.See example below:DSCR < 1Principal + Interest = $1,700Taxes = $350, Insurance = $100, Association Dues = $50Total PITIA = $2200Rent = $2000DSCR = Rent/PITIA = 2000/2200 = 0.91Since the DSCR is 0.91, we know the expenses are greater than the income of the property.DSCR >1Principal + Interest = $1,500Taxes = $250, Insurance = $100, Association Dues = $25Total PITIA = $1875 Rent = $2300DSCR = Rent/PITIA = 2300/1875 = 1.23If a purchase, you also generally need reserves / savings to show you have 3-6 month payments of PITIA (principal / interest (mortgage payment), property taxes and insurance and HOA (if applicable).

Quote from @LaShon Evans: Looking to get started this spring with the purchase of my first SFH for a LTR situation. 

This is more than enough to do PML's whether you originate or purchase from a broker is up to you.
