I would have roommates (and tenants if it was a duplex) who would pay a nominal rent for that area.Any input is appreciated, thank you!

3) If you see a property going to auction with a nominal opening bid for say $100k.  

Caretaker on site for nominal fee.  

They let you do a dozen or so before they want to start charging you a nominal fee. 

For a nominal $50 annual loan fee, I have access to my HELOC for a super-cheap interest rate.

I only considered the nominal price increases you might expect as an investor.

I always calculate the Nominal Cap Rate (this is what most people refer to when discussing Cap Rates, NOI/Purchase Price)) but also the Economic Cap Rate (which includes Cap Ex expenses).  

The property is to be sold for only $10K, and am asking for a nominal down payment of just $500.  

Odds are that a tax-redeeming owner will only have to reimburse tax deed buyer for taxes paid plus nominal interest.

I've paid referral fees out (usually a nominal some of the initial lease up fee) but the biggest thing is just making sure that their client stays their client.
