If you are renting by the room, I'd also get a cleaner in to clean the common areas.

@Michael Plaks Me too, but don't let that analogy carryover into promoting DIY TurboTax warriors haha.

I usually do this to help cover the carpet cleaning costs once the tenant moves out.

Why does it change things-- unless you're thinking cleaning, etc., but those were all sunk costs from the get?

In an attempt to clean up the industry, legislation was written by those who 1) had never been lenders themselves and had no understanding of the industry and 2) their biggest campaign contributors were big banks (look up Barney Frank, Chris Dodd, and Elizabeth Warren's campaign contributors at the time and you'll see big banks).

The answers to those questions will help you determine how DIY you want to go, and how much you can leave up to chance.I can't post links here, but for more, please google:"Why you need an experienced ADU builder" - case examples where cities asked for tens of thousands of dollars of work, or flat out would not have allowed an ADU project, except for knowing when to push back"ADU sitework & utility costs: 10 hidden costs" - dozens of costs you need to account for on your ADU project that I promise you haven't thought of and no one else will tell you about"How to find ADU builders" - compares DIY route vs. other options, plus more on what to look for in a good contractor

SUPER user friendly and very clean/sleek designs to help convey your point and content across to your audience.

Do I have to disclose to buyers that this was a marijuana grow house in the past even though everything has been cleaned up and there is no mold?

Then, look at any updates that might bring in MORE or HIGHER rents, such as kitchen, baths, fresh paint, clean floors (carpet or hard surfaces), ceiling fans, window AC units, etc.

This has been a journey for me and just want to make sure to stick with it and sort of clean up my portfolio for the better so we can see positive cash flow.
