i have a client who wants to bring in some UK-based partners for a year or two, and they can't find a house to rent. 

When I first started doing lending in Detroit.. this was an issue ... my client a big time flipper rehabber always had retired cops there with a clip board to check in the workers.. it was determined early on that much of the theft came from the exact guys that put the stuff in during the day.. they had the codes they knew what was there they would come in at night and steal it .the day cop and clip board put that to bed.So I agree with @Bryan Bannach  hire a retired policemen have him there during construction hours its the cost of owing property in the hood.. nothing unique about this.or just sell the property and buy something else.. but I think your looking to assemble so I know you probably don't want to sell.so just as stated hire security and I really like the idea of the @Patrick Liska  Cinder block fence I would for sure do that.. then put broken bottles in the concrete on top..

We have one client who demo scope of work usually entails about 2-3 pages it is so detailed.The next item is asking the right questions and get multiple references.

We transfer the client's scope of work onto our own template, this serves as the contract for the project.

You want someone who has clients that are real estate investors.Whether you get a tax refund is dependent on the tax you owe and the tax you've had withheld. 

Does anyone recognize this brand faucet / fixture? 

I tell people I do not have time as I am spending it on clients who have made a commitment to me for my time and services.If I make thousands per hour for my time then someone asking me for free crap is not only not bringing me money in it is taking money  out of my pocket because I can use that time for clients.What might be better is paying for ongoing consulting services.

I have doctors as commercial retail clients and they all make tons of money I mean a lot each year.

I tell ALL of my clients when they are looking for homes, not to do ANYTHING else until it is time to close. 

Once you start buying more properties and become more successful the more valuable you will become to the agents and the more they will want to work with you.I know it sounds harsh but I as an agent am going to work with the client who I like and who is going to allow me to make the most money in the least amount of time.Also consider getting your real estate license again so you can at lest start doing the research easier and have full access to the MLS.
