I just go in at the first of every month and code each line item to the corresponding property and note what the expense was for (Repair, HOA Fee, Mortgage payment, etc).

I am also doing a live in full renovation for a long term rental where I am project managing mechanical items and doing a lot of the interior renovations myself. 

Evaluate the depreciation of each item separately.

There's other items such as this where it may be helpful to talk to a CPA/EA for a little tax planning, especially since you'll likely get caught up in the passive activity loss limitations if taking bonus on a single rental property as I often see.It's also useful to mention that even if you do the cost seg study (I'm assuming you're doing one to be talking about this), you'll still benefit from accelerated depreciation in the form of shorter useful lives on the assets where you received bonus from.

Often times they come back with a list of repairs that they would like to see to protect the home or mitigate liability. 90% of the time those items were on our list to fix anyway, and sometimes we even haven't done before we get the letter from the insurance company.

Like you, when I'm working with clients I highlight the key advantages of the conventional rehab loans (Fannie Mae's Homestyle and Freddie Mac's CHOICERenovation) are:- They can be used for investment properties- You can include luxury items- They have a higher limit – $806,500 in most places.Jeff

Look for a place where you can secure items that you do not want tenants to have access to. 

My family makes a joke about how those items aren't "Nickproof") At this point we decided to call it and come back tomorrow.
