Has anyone use RUBS (ratio utility billing system) on a small multifamily property (say 10 units or less)? 

You are better off making a small investment on your own, maybe a two-family, and use it as a proof of concept.If you don't know anything, trying to source deals off-market will just be taking money and burning it on postcards without the correct systems behind and the incentive for people to call.

This is how its done.As a rental rehabber (for my own portfolio) I just need; a decent handyman who can do simple electtrical fixtures, plumbing fixtures, fix leaks etc, an HVAC if I plan on replacing the system, a roofer if I need a roof (rarely), a painter, and a lawn guy to clean up the lawn.   

So the ONLY GC's you will ever get to make this work with, are the GC's who are too small, too new, too green, too novice, to have earned the PROPER logistical system and account's to have obtained Manufacturer/Supplier direct pricing. 

I had someone who did somewhat the opposite, where they changed their mind and wanted 10' basement ceilings and did not check the grade with the invert of the sewer in the street and had to add pumps etc. to their system. 

They didn’t have the local knowledge or support system in place, and it quickly turned into a nightmare... constant vacancies, high eviction rates, and repairs that drained their cash flow.

Hi BP,Just wanted to get thoughts on different heating options.I need to install a new heating system in one of my apartment units (approx 580 sqft) but wanted to get thoughts on whether an Electric Wall Heater was a good option?

You can also look at our major highway systems and in places like boston they are leasing air rights over major highways for building as well.

One has no experience with real estate, however, does have experience with managing systems with a large company.

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.
