Brian Buffini's Peak Producer training was intrumental on teaching me to work through referral. 

I try to avoid this by "teaching" my tenants and help them keep on track with their expenses.

Hi Andrew, I think debt tolerance depends largely on the individual: I am still building a portfolio, so I have a higher debt tolerance than someone who is ready to stop building and concentrate instead on cash flow. 

However, I would recommend teaming up with people who do have experience so you can say you are working with experienced individuals.

That's what I've tried to teach my kids: "if there's a will, there's a way"!

Any individuals or resources you all might be able to point me to? 

Even the great tenants who are always on time don't change them or if they did it's when you remind them the third time after 3 months...I would give them 12 filters and at the end of the lease there are still 11 new filters and the original one completely disintegrated and become "mush" on the coil above it.So now I always change it every 30-45 days myself, and use it as a way to do a quick inspection of the property.But too many odd size filters for each property or each individual unit is a real pain.

Brian's teaches that stuff, though...Honestly, I've never been into "selling" sellers. 

Can anyone recommend an individual/company in the Denver metro area?

You can adjust the purchase price accordingly . . .).4) New Tenant Credit History - This may be obvious but; You need to verify credit history on the new Tenant; Make sure you have an adequate security deposit,; Attempt to get a personal guarantee if the Tenant is a corporation or partnership, and; Verify their previous "leasing history" with their current and previous commercial landlords. if your new Tenant is a startup, be cautious, make sure they have the financial capacity and experience to conduct their new enterprise and pay your rent and the NNN expenses.5) CAP Rate -Each market and individual property categories will have their own unique market Cap rates.
