Has anyone been successful with communicating with a lender to post pone a sale in order to get title work in?

So my lender was lagging a lot and therefore me and the sellers agreed to postpone closing date twice (we signed anAddendum).

But I got so frustrated with not seeing progress that I rushed things that I should have postponed.

Of course, the past is no guarantee of the future but, as this example illustrates, fortunes can be made by simply postponing gratification for a little while.          

Once you go one day beyond 3 years of renting you will have to pay capital gains or do a 1031 to postpone taxes. 

Normally, we would postpone the closing until the Seller can get the tenant out. 

She postponed getting the floors redone and I postponed investing until early next year, but she agreed to the cash out refinance.This phase also includes gaining knowledge and increasing your credit score.  

I've only been on my journey researching for the past month chomping at the bit to get out there and buy a home...however my wife and I signed a purchase agreement back in January on a new house build so I decided to postpone buying my first property until we close on our new home in October/November time frame....However, the more information I keep digesting, the more I keep thinking why don't I cash-out refi our current property and keep it as my "first property" to rent out?

If possible, try to get them out before you close, and postpone the closing until they do vacate the property. 

This is also literally the first time in my career as a landlord (about 100 tenants at this point) that a tenant has questioned a rent increase.Yesterday I got this email from them:I do not believe that after what turned from weeks to months of listening to power tools for the majority of our down time, a rent increase is a reasonable request right now.A postponement of increase until January would be 3 months from the date you provided, roughly the length of construction.We enjoy this apartment, and arent going to be leaving anytime soon.
