We just bought a medium sized multi-unit (64 units) and it was all based on income, i.e. what it brought in every month vs. it's expenses.

Getting out and firing a bunch of different handguns allows you to see what size, style, and caliber you like best.

The better loan are non-banks where you get non-recourse but typical loan size needs to be 2 million or more.So on a 2.5 mill property with 500,000 ( 25% down ) you would need reserves of 10% of leftover loan balance or 200,000.

I run into radiator/ forced air conversions all the time.I call my scraper- he removes all radiators, boilers, supply/return lines, oil/oil tanks for free, then I get my HVAC guy start running duct work--- Some of the boilers I've taken out were the size of a small car- not worth my time to deal with the little bit of scrap $$ in return.Find a good/clean scraper- they are an essential part of the team.

financing comes in all shapes and sizes.

Smaller size..?

I do not own a park, but I own quite a few mobile homes in parks, and I'm fully capable of operating a medium size(50-100+) lot park.I have a couple of guys who are interested in a JV. 

The size per unit based on the plan is 2,905 sq ft.

For two, when an appraiser is adjusting for size they will look at the average $/sq.ft. in the area and use that to compute an adjustment. 

I doubt the biggest cities (Portland, Seattle) would be the best options from a buy/hold standpoint, but look for the mid sized cities that are growing.
