Specifically at the spot in question too.Recommendation: 1) Have them send pictures of the mold.

Would you say that turning the current post off and creating a brand new post (with changed pictures + putting some sort of 'pets welcomed' tag) would help?

I would think a detection device would be easy to fool or disable, and difficult to prove in court.I would focus on inspections and look for the following evidence, then document with pictures, written warnings, demands of cleaning/repairs, and follow-up inspections.

We would need to see the full picture and discuss the details before being able to provide good advice.

We are not qualified or set up to calculate a financial picture in the same way a lender does, but we are also not evaluating the same level of risk.

I just want help or advice on building it from the ground up and not getting overwhelmed by all the options at once and take baby steps towards the bigger picture.

Transparency always wins.3)Make sure to have mattress and pillow protectors, top-notch cleaners that take pictures of every sheet as they lay it before guests get there, and consistent pest control.

@Bill AlpertI looked at your listing, pictures & description on MLS.

Make sure you have funds set aside for an emergency, if you have personal debt, try to eliminate as much as possible, understand what your personal balance sheet looks like in regards to monthly cash flow and net worth.Investing in real estate is investing in a business, and you need to have a good understanding of your financial picture before you begin to buy a business.I would then focus on what niche you want to start with.
