Whether it's building your reserves, investing in other areas, following the market trends, etc. 

Hmmmm so there is a trend then...good thing.

The building seemed to be in a declining area and the quality of tenants in surrounding properties were trending in a less than favorable direction.

The main driver or housing price growth in 1960-1990 was incomes growth, the M2 money creation (the greater liquidity in capital markets) and the new loan options: Freddie Mac and ARM loans in 1980, but not the interest rates that skyrocketed by 1980s.The same trend continued until 2009, when the impact of the 2008 GFC was so strong that despite relatively low interest rates and continued M2 money creation, the incomes dropped following by the housing price bottoming in 2011-2012 (2-3 years later).

Many partnerships often do a 50/50 spilt - one party supplies funds, the other all the work.More sophisticated arrangements, like syndications, trend to 80/20 or even 90/10.You're situation is more complicated as you'll be living in one of the units.

Pick the trending city that is closest to you, then open Google Maps and look 2 towns out in each direction and see which one has not hit yet.

Market Trends How did you finance this deal?

I would be careful about adjustible rate debt in general, because with inflation it's looking like they're on an upward trend, although still lowYou'll want to work with your CPA on setting this up & any tax questions regarding the interest payments, if they'd be debt service on the new propertyThe longer you need the money & the more money you need, the more likely a low fixed rate mortgage would be the better option, [between that and an adjustible home equity line of credit (heloc) if you're considering the 2 types]But some banks offer a loan within a line on their helocs - if you use a big portion of the line you can call them & fix the rate have a scheduled payment each month, which includes principal.  

Would you say the trend is still toward more restrictions in most places or less? 

Hi,I would like to know is there any specific website that I can find the RE trends of different US cities over the last 10 or 20 years?
