Should I price the land 2 times above market value and offer a low interest rateORPrice the land at current market and use a very high rate?

I was recently sent details about a 20-unit apartment complex that I’m interested in, but the seller's asking price doesn’t align with the numbers I’ve run.

The barrier to entry seems high, and the price-to-rent ratio isn't very favorable.

For example, most Developers in the Seattle area are taking many properties and turning them to condos since that is a booming market with high rental rates And sometimes more conveniently built and accommodating then a SFH.

Demand is very high, both for rentals as well as for sale and this is probably not going to change.

I would protect myself and cut my losses so I was not looking over my shoulder or getting high blood pressure every time I heard a knock on the door (hoping it is not the FBI showing up to ask you some questions). 

It should be pretty accurate - high level data sites are not always going to be perfect, but should always be directionally correct and AirDNA has a pretty strong track record. 

The credit back helps set me apart from other landlords in the area.

I have a template that I provide and they can either complete the template or just give me their documents and I'll complete the template before prepping the taxes.Self Managed, High Volume, Very Organized - these folks keep up on their activity.
