I've had them do panel replacements, pull new circuits, install recessed lighting, etc. 

I recently installed Carbonic Heat in one of my buildings. 

I drove by the property tonight and noticed a brand new vending machine installed on the sidewalk by the front door of one of the tenants.I know the property owner/manager didn’t approve of it, so it must be someone that works for the tenant that had it installed.The office building is a 225 foot long single story building with 3 tenants.

It's called a Monetized Installment Sale. 

You must know all the rules and don't get upset when sometimes you mistake and pay few $$ because you forgot about expiration of 0% Right now, business credit cards give me 0% till March 2020 and with only 1.99% fees upfront while personal cards only for 12 month and 3-4% upfront.This is long term game and ideally you have to have 4+ eastanlished credit lines with different use - revolving and installment, for more than 7 years - never be late - then you'll reach to 850 FICO.Plus few other tricks - but it's alittle bit personal

I'd like to install 1 or 2 security cameras at my rental property.

Also 3k for an add on room, That must be a big room . 200 per sq with materiel installed  is what you should pay, no more. , DO NOT return the SD, 

Its based on what the future value will become with the rehab installed.

It was a tight squeeze setting up pump jacks to install siding, but we made it work.

I had a French Drain installed, basement became completely dry.
