This letter will serve as proper XX-day notice that we will not be renewing your lease for another term at that time.

Do you have collected any certified letters of tax notices sent by the local tax collector?

I went through everything until manually signing 300 letters and sending then off to only receive one single call back from a curious guy looking for a make me move offer. 

I recognize that the CoC return is not as high as we'd like, but it does come with some built in equity (~$100,000)Details:- 3/2 Single family house (1487 sq ft) with a 1/1 ADU out back- Zipcode 78745- Purchase price: $469,900- Down payment: $50,000 plus CC (includes assignment fee)- Seller Finance $419,900 at 3.5% interest; 30 year amortization with a 15 year balloon- PITI $2744.02- Rental comps: $2667 for the 3/2; $1505 for the 1/1 - LTR according to BP (Total $4172)- Repairs needed - minimal, coat of paint and maybe swapping a window unit A/C for a mini split

I only received a letter from the appraisal office saying that the value went up but no notice about my taxes going up by 50%.

Most tax preparers include in their engagement letter that you have ultimate responsibility to what is reported on the return.

It says in the welcome letter they are required to read it and by staying at our cabins have agreed to the rental agreement.  

I always make my offer and include a POF(proof of funds) letter showing the seller that I have the funds to close.

During that time, I received a letter from the City of Lorain about some violations, including overgrown grass, missing handrails, window frames, and not pulling the necessary permits.

They should write you a letter explaining the error and that they are going to charge you the additional $400 now.
