From that information I would think the best you can do is get a range of the ARV (say $150-$170k) and I would make sure you numbers work no matter whether the actual value falls within the range.

I am a new multifamily investor (5-20 units) along the Front Range specifically Boulder and Jefferson Counties and am having the same issues when it comes to getting quotes.Brokers and agents have told me that some areas near us are simply uninsurable now.Most owners that I meet have are still in policies from before the fire.What have you learned in the two months since posting this?

We found a small duplex within our price range and found it worth it.

I also personally feel that Indianapolis has a more stable/diverse economy and more inventory for investors. 

The condos I am looking at range from $110,000-$140,000.

With very low inventory levels due to covid-19, sellers have taken their homes off the market in large quantities.

A fair interest rate for seller financing typically ranges between 4% and 6%.

Rates currently range from the high 4.00% - mid 5.00%'s depending on the asset / borrower / location. 

Not saying its a bad deal based on loan terms because it might make sense just know as an LP what you are getting into.Market Type & Competition:Determine if the property is in a primary, secondary, or tertiary market.Evaluate supply and demand, focusing on new inventory coming online in primary and secondary markets versus more stable tertiary markets.

Once you highlight a couple of locations, pay attention to active inventory in the areas by going to listing sites and checking out properties for sale.
