The only difference is the structure? 

Definitely get the structural engineer to look at the joists & support beams to see what's up with the uneven floors.

Very common to have structural issues caused by soil movement. 

@Sofia De Santos Tavarez if you haven't already, have the property professionally inspected.This should catch MOST of the structural, health & code issues - but not all.

You will be forced to solve problems and get scrappy which will carry through all the next phases.Then, I would see if I could possibly start with an addition, garage build or other small and simple structure for your first ground up -- I started with a 250 sqft master suite addition.

Sometimes pulling out equity and reinvesting it elsewhere..maybe in a smaller, more agile asset..can give you the cash flow boost you’re after without giving up a solid property.Improving the property’s current performance by making it more appealing to tenants or tweaking lease structures could give you a nice bump.

While it’s certainly possible, the reality is nuanced and depends heavily on how you structure your investments, manage your properties, and account for the inevitable costs of ownership.1.

You can only play games for so long.Chances are your next door neighbor is an IRS agent and turns you in when your tenants blocks their drive or some other random event disturbing your IRS neighbor.ADU catches fire and your insurance won't cover you, because it was an illegal and unpermitted structure.The city inspector told the last guy not to build or rent it, and is now pissed and wants to make an example of you and just red tags the whole property and no one can occupy for the next 1-2-3 years while you wait for a hearing.Then when you get the hearing, "staff" recommends you tear the whole structure down, and if you still want an ADU, you can apply for a permit and rebuild it.Your tenant quits paying rent and won't move out and you can't evict them, because there is no valid lease and they're just your "roommate".Probably a dozen other bad things can happen to you when you do stuff like this. 

This sentence, for example, seems completely unnecessary: "Thank you for your time and attention to this matter.

@Jeff Love Here are the things that many CPAs support their clients with:Understanding tax impact of short-term vs. long-term vs. flip before you buyWhich entity structure is best for goals and investment property typeTax and compliance on LLC or S-CorpHow to transfer property out of personal name into LLC (hard to buy 1st through entity)Ways to optimize taxes throughout the yearHow best to set up accounting to track income and expenses (doing this late is a mess)Feedback on property management systems, accounting systems. systems, etcEstimated payments to avoid penaltiesKnowing when to file and getting things in on timeMaybe a few things I missed, but this is the high-level ….. if you can get answers to the above questions on your own, plan, and file your own taxes then you can avoid the expense of a CPA.
