To do that, you should find the historic rental rate increases for that area and multiply it out for 2 or 3 years. 

The historical average appreciation over the last 40 years has been 6% per year in Denver metro (which includes Littleton, Highlands Ranch, and Parker and those cities listed above).

I bought a historic home in Northern AZ and did not have a lead paint inspection.

With oil at historical lows I see this as the perfect time to buy low and potentially sell high or take advantage of the insane rental market during booms that will come , as they always do.

It's original hardwood floor and as you may already know, the house here is historic and very old.

It probably needs $40-50k in mainly cosmetic upgrades, but the un-permitted areas could make selling difficult.I'm not familiar with this area, whether it's historic or not, or if it would be difficult to get permitting for additions done 60-80 years ago.  

@Melba Chambers  Historically 15 year mortgages have lower interest rate than 30 year mortgages. 

I have done some digging around the old posts and historical discussions and it seems to me that the latest posts I could find were from about a year ago (Jan-Mar 2020). 

(one street is filled with expensive historic homes, the next street up is ghetto enough to feel you need to pack heat). 

That’s because the Bay Area housing market is historically strong and rents increase nicely over the years.
