You aren't "almost/sort" functioning like a real estate agent... 

Lastly, I urge you not to make the mistake of thinking, just because you do the property management yourself, that the expense of that function magically disappears!

I just need some basic functions, tracking rental income and expense categories.

Functionally it is another line item expense that you need to account for in your projects and if two homes rent for the same amount and have roughly the same tenant class and expenses other than taxes, than the taxes will be directly affecting your bottom line of cashflow.On flips it matters less, but is still something to take account for in your budget and make sure that plenty of homebuyers are wanting to buy in the high tax area. 

Buildings over 100 years old are usually written on Functional* replacement cost because it’s hard to perfectly indemnify 100 year old antique masonry.

The property was in a fairly good state but need minor repairs to trim and door function.

You'll want to zero in on cities with largest amount of multi/commercial type properties that meet the criteria, turnover rate, and how what is the timeline to execute and deploy those funds in a thoughtful manner for long term growth. 

We do primarily custom work, and so really need team members that know their craft and can view the blueprints and function independently and autonomously.

As it is the kitchen is functional but I personally would like the space more if it was updated.

(some may be concern more with aesthetics, some with functionality, and some with being cost effective: so you have to understand and know what combination of all of that and balance of those you want for your project). example: sometimes I work with home owners or investors that want a good balance of those... or sometimes, some clients say to me...Sebastian, I don't care about saving money (I don't want to over pay) but I am not concern with budget to a realistic extent. :) I also saw: 4900 270th Ave NE, Redmond, WA 98053Listed for $700k (2500 sq ft) but it looks to be a fixer : @ $277 per sq ft with a huge lot: (I don't know if the same market as the home above: and where your realtor would come in... ) but if you look at this: you could buy something like this and renovate it: and add the ADU : 1000 sq ft for about $150k to $200k all in: where you spend $100k on the main home: and now you are all in for $700k + $100k +$200k : total $1 million (which is less than the finished home above).
