I spoke with two lenders who they suggested and the lender I normally work with and I could not qualify with my primary home and rentals.

Normally, it's offered to the other partners first and they can either both buy it to equalize the partnership or maybe one can buy it to take percentage ownership.I think you could handle this through a real estate attorney easily.

Therefore, I wonder if an earnest money deposit of $50k is normal for a newly built single family house? 

The $1300 does not seem out of line at all to me, insurance right now is going through the roof and what would have been ludicrous last year is now looking like the new normal. 

I normally go into a deal telling a borrower to expect 70% LTV and then if the appraisal comes back suburban then we can bump up leverage. 80% LTV is typical in suburban areas and 70% is typical in rural areas for DSCR lenders.

We made to make some upgrades to cover the number of people but haven't had any issues other than normal maintenance yet. 

Normally, I would agree with you on that statement. 

It is normal to get cold feet but the main thing is to do the best due diligence you can do prior to going under contract-  "Pre-DD". 

That is reality because the receiver of the info has no skin in the game, nothing to  hold them to the "advice".

I think it depends on the market.. they approached me on a furnished rental I had in Vegas (Summerlin gated community A class)  We got basically double or a little more of the normal rent..
