I had an Excel sheet where I kept track of every individual expense/rent payment for my first rental, but I just bought 2 more units and now I've been working on building a more robust version of the sheet that can handle multiple properties.

Does this cause extra filing?

Looking for all types of investors, agents, and like minded individuals who are interested.

I've been flipping back and forth between what I think is best for me, just wanted some extra insight from people who have been in my shoes.

In my personal experience (might have just been the individual and not representative of the company), they did not get up on the roof, they did not get into the crawl space, and they missed a handful of minor but worthy issues I would have noted inside the house.

Well, you can either hold the property in an entity (LLC), or as an individual/trust. 

Only one primary residence per individual or married couple qualifies for the Louisiana Homestead Exemption. 

After closing write a lease transfer or new lease agreement with only change in Landlord name & contactGet all the tenant deposits, extra keys & pro-rated rents at closing.

Also, when structuring your lease, take his/her extra expenses into account too. 

So even if the average is $1050 that doesn't mean that houses also couldn't go for $1250 or $800 in the same area depending on its individual characteristics.3) It's not entirely clear where Rentometer pulls its data from, but I think they are using list prices instead of actual lease prices.
