What they could have done better is referred me to a better PM, who actually does better work, they could have helped me in analyze the property better, they could have atleast helped me get a property which does not loose value over time but gains it(which they clearly lied to me about).

No excessive fees upfront or during holding period4.

The new released estimated total of the effected areas is now in excess of $250 Billion.

The agency, of course, is trying to maximize its resources, so would love to have you charge less rent.If your focus was primarily on gaining excess rent, keep in mind that there is a reason many landlords will not take vouchers.

Its a tough subject because logically, they are joint and several guarantys so rationally a 100% guaranty from each of two people (one 740 one 680 for example) is ALWAYS going to be better than just one 100% guaranty from someone at 740 (so it wouldn't make sense to have a better rate for the latter)The problem is that there is fraud and "straw borrowers" out there where someone who is not involved in the property signs on to boost score and terms - so many DSCR Lenders in response either do the "non-rational" thing and price to the lower to avoid the fraud or use the higher of the two (and either be a little loose with things or just stay vigilant on any funny business)

Assuming it will be Single Member LLC (you as a member/manager), it will come back on your schedule E anyway, so only thing you loose is $800 in california and bit more of paperwork but that preps you for future.Note - this is a very high level advise and mostly a personal preference.
