I WILL keep this short.I am 23 years old, me and my Dad have been investing together over the past 4 years in real-estate....we just closed on our first deal which was:275k Home which we bought for 255k......That home is nice but does not cash flow and just pays the mortgage. 

Many are left with a home that is worth less than the current mortgage. 

Thanks,Ratna what everyone mistake is some people is stuck in h1b for decades and they are too afraid to buy primary home, or to buy rental in US or even to apply mortgage which at the end, makes them losing the biggest opportunity to make money in real estate.In reality it doesn't really matter as income from cash flow is a passive investment, you could do even flipping business while on h1 as the profit is from buy and sell activity. 

Here is a summary of the book.https://www.nateliason.com/notes/long-distance-real-estate-investing-david-greeneThe book also mentions the importance of having a rockstar Realtor, contractor, lender, and property manager.

Does anyone have recommendations of a good lender in the area?

The appraisal is usually issued for the benefit of the lender so you can play hardball and share that the lender will not release a copy of the report until after settlement (which does happen in some instances depending on the lender and their policies).

Part of a lenders Short Sale package, is a Short Sale Arm's Length Affidavit which is signed by the seller stating that they are NOT related to the buyer.   

A business banking account integrated with options for lines of credit, commercial mortgages, or construction loans can be very attractive.5.

If so, now I'm seeing lenders willing to do DSCR loans of 75% LTV, so then would I switch to say 75% Rule for analysis?

Here is a list of lenders specialising in such loans:https://www.biggerpockets.com/member-blogs/2810/50272-list-o...
