I wanted to know if it would be wise to buy a reasonably priced home and do house hacking.

I believe Nev is a brick and mortar state meaning you need a physical office there to broker mortgages there. 

You will need to buy the tax certificate at the tax lien sale.

I just wanted to get some insight on how common it is to request mold tests prior to purchasing a property and testing for mold with long term buy and holds in this climate.Thank you in advance! 

Are you looking to get an investment property at 20% down or a primary residence you can house hack (rent the rooms in the house you are living in), or a primary residence (better for people who are married/have kids/don't want roommates) where you live in it for 12 months then rent it when you buy your next property to repeat the process.

Depending on where you want to buy there might be better loans than FHA, BBVA for example has a nice loan called HOME that has something like 3% down and no PMI, depending on your income and where you want to live.

BUT, if I could potentially get the seller to buy down my interest rate in closing, that could increase my ROI to just over 11% and increase monthly cashflow by ~$45.Thoughts?

Unless you own the house cash, in addition to the advice you've received, you can't just transfer a house from personal to an LLC without risking the option of the loan being called since the LLC does not have two years of tax returns.For new investors without cash to buy, LLCs are about the biggest cause of analysis paralysis out there.

However, since we don't have any experience in rentals, we don't know if we should buy a single home and get it rented out or buy a multiplex.

This notice stated that a re-inspection would be carried out 12 days from the mailing date and advised contacting the code enforcement officer prior to the inspection date to discuss informal resolution.
