I agree that one CPA should suffice.

@Chris Mason would it possible for the LO, underwriters, etc to go through a whole loan on a 4 unit, miss the self sufficency test then not be able to sell/insure the loan do to that?

Suffice it to say they typically will last 15-20 years, will cost between $1000-$3000 to replace, and depending on the type will need to be service every month to every 5 years. 

@Jennifer Van vlymenThere are several considerations that can go into the analysis of whether you need an LLC or whether a large insurance policy will suffice.

Maybe just asking for a signed document from the tenant about the basic lease terms (rent, security deposit, lease end date or mtm) might suffice.

If you’re looking to limit costs, Microsoft excel/ google sheets should suffice.

I have the sink, is a mini fridge sufficent.. do I need a full size fridge, stove/oven ??

Traceable income may suffice without a lease, but you do have the issue of not reporting the income on your taxes.

If you don't know them very well then a text or email will suffice.

Seems that one account would suffice with the proper accounting per property.4)If I am going to first purchase these properties in my name but later have them setup in an LLC that will be created at a later point, how does this effect the account?
