The 8 mos isn’t quite long enough to utilize just the STR income to qualify but many lenders allow AirDnA projections to be utilized as the income to qualify.

My partners and lenders would laugh me out of the room if I told them the property doesnt cash flow and just look at appreciation ... we only look for cash flowing assets and "hope" they appreciate along the way. 

In terms of doing a refi the house would be compared to others of the same value and adjustments made for BR or SQ FT. 

There hasn't been this huge wave of foreclosures or short sales as people are hanging on, doing cash-in refi's or doing work outs with lenders.

Especially A lender as they are notorious in this business for being full of crap. 

If you cash out equity in a property, you are "borrowing" that money from the lender.

Many portfolio lenders offer 30 year terms for multiple family.  

@Melissa Odom private money has been awesome for me and helped me grow my portfolio tremendously.We used it to do BRRRR where we bought the property with private money, rehabbed it with that money too and refinanced as soon as we could to get them their money back.Our private money lender was happy because they made their return and didn't have any worries because we were an easy borrower.

or any recommendations on which is the best Bank/lender to get one with the best rates? 

New build lenders want to see your 3-5 year experience with this type of a project.
