For example, if your IRA puts down 60% and finances 40%, roughly 40% of the net income generated will be subject to UBIT.

@Landon Dolezal - Brandon Turner had a webinar this week (5/25/2016) and used a four-plex in Washington as his example for deal analysis.  

For example, if there is any significant deferred maintenance, I would want to back it right off the purchase price at the very least.)CFBT: $5,597.60Monthly CFBT: $466.47@Ola Dantis - You came up with a much lower cash flow than I.

So for example, if all 4 of the HVAC systems in this 4 plex are 10 years old, and the typical lifespan of a HVAC system is 20 years, then you can assume that you'll likely have to replace those HVAC systems over the next 10 years.

For example, property tax in Oregon is really high, but there are no consumer sales taxes.

For example furnace, water heater and appliances all have limited life span.

The previous post (2 before mine) is an example of why you must be careful of who you accept advice from.

I see all over the internet a short answer of no, but what about the following situations:1) example: you invest 10k from IRA and 10k from personal bank account to purchase a property.

They seem like pure liabilities with no use.An example is here.  

Essentially is as follows:New Lease Fee (one month’s rent) + Expected Missed Rent + “Refresh” Cash(Refresh Cash = the amount out of pocket to prepare the property for new tenants, after tenant deposit is spent)It looks like this:(A/B)+(A*C / B)+(D/B)Where:A = New lease fee (1 month's rent) ($1,000)B = # of Months in lease (24)C = Expected # of months vacant in-between tenants (1.5)D = “Refresh” Cash ($500)In this example:($1,000/24) + ($1,000 * 1.5 / 24) + ($500/24)Which is:41.67 + 62.5 + 21 = $125    which is 13% of monthly rent in this scenarioThe equation allows me to make a judgement call in many different scenarios.
