You will not get cheaper money that what a HELOC would cost today but the interest rate is adjustable so it's a moving target.  

I wanted 12 -18% cap rates (interest rates were MUCH higher), and real estate I could buy for 25% + below REAL value.Immediately after the crash of 2008 I sought properties in the most devastated areas (Phoenix, Miami, Las Vegas) that were (1) class A (2) one third previous sale price (3) 8-10 cap rate on residential.Now I look at properties with a steady cash flow (depending on risk and property type), have rents that are short term adjustable in case of high inflation and have a potential equity "kicker", such as neighborhood being developed, restrictive zoning, university expansion, etc.I now divide my portfolio in three areas, not always mutually exclusive.  1- short term mortgage notes or long term mortgage notes purchased at large discounts (secured by commercial properties) for cash flow.  

The housing voucher family must pay 30% of its monthly adjusted gross income for rent and utilities, and if the unit rent is greater than the payment standard the family is required to pay the additional amount.

But do keep in mind that there are a lot of variables go into the formula here so you'll have to adjust with actuals and your own unique situation.  

 : ) Of course, you would need to adjust for inflation, from 1982 to 2016. 

Over the last two years I have bought and renovated two properties in a neighborhood in pittsburgh that has seen intense appreciation and have built up something like 225k in equity.My current high level financials are: Own two properties, both mortgaged and rentedConservative total market value of all properties: 550kCombined debt on properties: 325kTotal equity: 225kMonthly gross rental income: 3.4kMonthly net rental income: 1kI bought both properties on traditional non commercial mortgages and I have an 80k heloc alll factored into the combined debt number above.

If you go out of your 7 block range or so then you'll need to take into consideration what kind of an area your using as a comparable is it better or worse than your area and make adjustments for that.

So I am earning $2750 more annually on my $100,000 from private mortgages than I would be from treasury bonds on a risk adjusted basis 

If it doesn't work, then adjust your strategy, but keep taking action.

The pertinent piece for me is the right to cure every 12 month period in terms of getting better tenant compliance because their option fee is now at stake instead of just one month of deposit.What I realized that I need to adjust in my Excel model is that I would be entering a contract to sell the property now for an agreed upon value greater than current value.
