You're a speed demon. 

If you are used to this kind of tenant, you will have a big adjustment to make when you buy, a, (or several?)

You should be able to request things about the reserve study - such as whether the HOA has ever had a study done, how recent, what items were included, is inflation accounted for, whether inflation adjustments have been compared to today's actual costs (imagine cost of materials jumping due to shortage from high demand), etc.

Many older homes have unnecessary walls and funky layouts, so I just adjust those to make the most of the space.  

In hot markets, speed is everything, and before 10 people can view a property, I have already done a quick analysis which includes some assumptions, and sent in my offer.

You can look up a property's exact current tax bill on the Cuyahoga County Auditor's webpage here: http://fiscalofficer.cuyahogacounty.us/AuditorApps...Property taxes typically adjust upon a sale and revalued based on the new price.

I would have to find something that takes away the need for adjustments in that regard.

You often get poor information about their prospective incomes, and by the time real information comes out, the stock price has already adjusted near instantly. 

Given you are looking at taking down several properties at once, a commercial loan would offer the most flexibility and likely speed to purchase, but the terms likely won't be quite as good.  

But that option is less common.The renegotiation date is when the monthly lease will be adjusted (inevitably higher).
