I'm a newbie looking at house hacking and currently got conditionally approved to purchase a 350K 4plex in the state of Texas .However, the loan officer wants me to write a letter of explanation, apparently to be sent to the underwrites concerning my work history.

I know when you go to the e corp website in Arizona it does not give you the persons name or mailing address.

The taxes are a concern. 

Others will chime in and say "you aren't advertising the house, you are advertising your interest in a contract", however once you show photos of, specs on, and address of a house, you are advertising the house for sale. people seem to do it all the time, but I would be careful, as it seems they are cracking down.You have it under contract... your inspection period should be spelled out.

Within a couple of days we noticed a scam posting of our rental with our pictures and description and address but listed for $800 instead of the $1000 we are asking.

The other reason is that it makes it a little easier to self manage......as far as the tenant is concerned, I'm the manager and a company owns the property. 

The numbers currently make sense but we are concerned with the potential Health risks as well as how this could effect us being able to rent the units in the future or selling  the property a few years down the road.

I've never written a PSA on a property without an address.

Should I disclose the property address on the flyer?

I much prefer a lower cap rate in California knowing there is a high likelihood of long term rent growth and capital appreciation vs. concerning myself with a higher initial cap rate in the midwest but on an asset where rent grow is small and an asset that is deteriorating.
