Just give them the details of the property, beds, bath, garage, exterior, age of roof, as much as you can, your asking price, whether seller or buyer pays closing, and the rest is on their end. 

Going to newer homes in better locations and letting someone else deal with an aging asset is a much better plan, especially as you reset your tax depreciation and learn to do cost segregation!

As mentioned above, Denver can be a challenging market to get started investing into multifamily homes.

I have my story, the struggle, and the journey from when I was a poor kid growing up, then when I began investing from the age of  22 or so to today at 31 years old where I have attained what in my perspective is success through real estate which impacts several categories of my life.  

I am glad you mention the price and days on the market.

I haven't given up, but I will tryout the list you mentioned..

I recently considered a service that basically does what you mention specifically as "corporate housing" with companies, but never went further into it as I ended up renting the unit out to some normal folks.

This was a great tip mentioned in the past 2 podcasts.Cheers,CB

Also, like @Matt Garboden mentioned, the outer portions of the city still have quite a bit of deals.

Where you are looking in Dublin (not sure if that is but that's what you mentioned), duplexes are going for over $200k and three units depend based on square footage.
