You would want to check local zoning to make sure you could build more than one as a lot goes into that beyond just being close to plumbing, electric, and gas.When you mention "a lot goes into that beyond just being close to plumbing, electric, and gas," what are the top things people tend to overlook when preparing to build ADUs?

I was using an insurance broker that helped break it down for me based on if I was planning to replace anything right away or wait. 

Every system you try will have flaws, or you may salivate over a feature that appears in other software.Some familiar names are mentioned frequently: Stessa, Apartments.com, RentRedi, TenantCloud, Innago, RentManager, Avail, Rentec Direct, Doorloop, etc.I recommend conducting thorough research on each app online to understand their offerings, pricing, etc.

We're still waiting to find out when we can apply and who we apply to, etc. 

I tried to look up your post you mentioned but you have so many threads here I wasn't sure which you were directing me to.anyway, I am in contact with a surveyor.. but waiting to sign the purchase agreement before I get the ball rolling. this property is in city limits and have been on contact with the planner. the 5 lots are within their parameters, this will have to be on city water and sewer.

Not sure if we can mention names specifically here in the forums so you'll want to search Google for rent collection for landlords or similar.Highly recommend having security deposit and rent hit a separate bank account from your personal. 

This deal that you mentioned sounds at first blush that it's dead in the water because of the large deposit.

I just finished working on it and waiting for their tech support to help me publish my website under my own domain. 

As others have mentioned you could have a conversation with your tenant(s) about splitting the cost.

If the sale goes through, we are making a substantial return (hundreds of thousands of dollars).My spouse and I want the money now and want to avoid the wait and see.
