Since I'm a new immigrant with no credit score, a DSCR with 30-35% down payment is my only option, so the 50K need to include that down payment alongside all other costs (closing, rehab, etc). 

Since you'll be owner-occupying, take advantage of low down payment loans like FHA (3.5%), Conventional (5%), VA (0%), or a 203k loan for renovations.

I was told by her that you first have to put a down payment on a property in order to see the inside?

In any disputed court action where the court resolves the dispute and determines the prevailing party, the court shall also award to the prevailing party its reasonable attorneys’ fees and costs and the non-prevailing party shall be liable to the prevailing party for payment of any court awarded attorneys’ fees and costs.

Is $50k-$100k your targeted purchase price for a property or the amount of your down payment?

Any one of us could give you our two cents on the math of it, but only you can decide if it makes sense based on what your specific goals are. personally, i paid points on my house because my goal was lowest possible monthly payment.

Bank pushed us to 40% down payment so also executed a $85K seller carry-back loan to cross the finish line.

I've seen a situation two years ago where a new landlord had trouble evicting a tenant who was constantly late on payments because the tenant argued that the late payment terms in the lease had not been honored since the start of the lease and couldnt be suddenly enforced because of this. 

In those cases where a tenant suffered a minor setback and is back on track, if they are scheduled for a hearing before they're evicted they will often pay before that or when they see the notice on the door, but only if you file relatively soon.It really is good screening and filing quickly and consistently that minimize nasty non-payment issues in just about any kind of market. 

The new buyer puts down 10% as the option fee, ($50,000 fee to our buyer) in this case, and we make the rate 10% to the new buyer for the monthly payment.
