If you're looking for investment property and want to choose a property with the most likely chance of getting hard money or conventional funding, look for the following:
Income producing - choose a property with sufficient cash flow to cover the monthly expenses of the property including any loans.
Structural quality, pride in ownership - choose a property that has been well cared for and one that you are willing and able to continue maintaining. If the property has not been well cared for in the past, consider what you will do to improve the property.
Future potential - look for properties in neighborhoods that are improving, or that support businesses in a growth industry. Look ahead 2-5 years to see whether this property is likely to increase in value.
