You also risk pushing the closing date, which can cost you money if the rates are moving up.Obviously it needs to be addressed, but not closing is costing you while rates rise and you aren't collecting rent money.In business, time is money.

1) I am not emotionally tied to my properties or tenants...2) I would sell a stock when it peaks the same way and look for the next rising star3) My net worth gets me loans and when it is tied to great appreciation it only makes me as strong as the market, so cashing out on unforced appreciation I protect that net worth number BRRRR is the only way I would be investing in the market right now.

The purpose of this would be to lock in on a good deal ahead of interest rates rising and pay it off in 6 months or less. 

I have too often seen vendors giving widely inflated classifications to properties, such as B+ to what is only a very average house - C or C+ at best.  

Doesn't surprise me, flipping work best in rising to hot market... but could be falling knife after the peak.

So far: quarterly % change in Real GDP, YOY % Change in Monthly home prices, job growth, interest rates, population shifts, rising wages, area revitalization, relocation, marriage, family growth, divorce, death, debt, active inventory, sold homes, avg. sold price, average days on market, Concentrations of jobs by occupational category, average level of education, school rankings, crime, appreciation, property tax rate, state tax rate, positive/negative RE legislation, monthly rental income, average age, inflation, popular property types and configurations, vacancy rates, volume of rental units added to market, time to rent, months of supply, volume of new home construction. 

Most owner finance offers are from investors and catered to those with bad credit, so few choices, so these properties generally  are offered at inflated prices and interest rates....not generally any bargains.

The market has priced the risk of rising interest rates in the interest rate charged.  

There are many reasons for this: punitive taxes, inflation, political changes, corruption, exchange rates, lawsuits/predators, etc.An offshore carrier with a policy denominated in US dollars would likely be a great vehicle for financing US investment... if you could get a loan in the US that is secured by an assignment of collateral against a cash value policy held offshore.

Plus, 2% from a bank is the best I can find and that doesn't keep up w inflation.
