Since your units are new construction, your costs will likely come out on the low end of that scale, especially during the first decade. 

However, scale and the ability to regularly pull in multiple guests and revenue streams in a month in a hotel distinguishes it from an apartment or condo.

I have my sites set on acquiring 100 units by the time I am 40 (8 1/2 years to go and 94 units to go)...I am looking to connect with someone who also has a similar goal of buying and holding on a large scale like me.

These tenants also tend to tip the scales in the amount of junk they leave behind.

I'm more interested in smaller scale tools that can provided value to the home gamers.

Yes there is the economies of scale with multifamily but who will you sell to when you want to sell?

At this stage I think we'll probably just go forward with things the way they are and try to get the property paid off in the next 5 yrs so that we don't have to worry about the fluctuating interest rates.This is why we started on such a small scale after all... so we could learn the ins and outs with minimal $ at stake.

Unless you are buying 10 doors at 80k to 100k a door or more for strong class B location and construction then you can open yourself up to lots of trouble buying from afar.10 units is not scale able from afar.

The scale of your development (large scale apartment complex or individual singe family housing) will determine the method that you would use to locate any utilities. 

You may have an inaccurate idea of the time scale involved when people say "rinse & repeat".
