Although I collect rental income from our long term tenants, the lenders consider it "Border Income" and will not count it.If I buy a STR, will the income generated from that count as income when qualifying for another mortgage?

It could be for any strategy--not just STR...There's a money partner and sweat-equity partner (I'd say "managing" partner in LLC lingo): the money partner initially collects all profits in a scheme where the sweat-equity partner works off his or her half of the initial downpayment in what Carl calls a "mini-mortgage." 

You’d probably still start with your insurance, give them a copy of your notice/documentation, and let them collect.

The company I'm working with won't count rental income until it has been collected for two years.

In my opinion they should be collecting my lost rent as my priority #1 and if they are able to collect their listing fee from the tenant on top of me getting paid on my losses from them good for the PM. 

I understand that you can only transact as the principal, but can you collect commission when you buy?

A portfolio loan is where you take more than one property and finance it collectively.

The rents they collect during the month of october is insane and using it as a reason to get out of town and do something fun with the family, I thought, was a great idea. 

The plan as discussed with both realtors was to have the current owner collect the November rents  and then hand  those to the escrow company.  

If you want to buy it in an LLC you will lose most of those benefits.I’m no expert but the Pro’s of owning properties in an LLC do not compare to the pro’s of buying as a personal residence.I’ve done 3 househacks so far and collect via Venmo linked to my personal bank account.
