What are the usual terms and conditions that would make a loan offer appealing when rehabbing or flipping ? 

Without knowing the specific terms of the purchase contract and exactly what point in the contract you’re at there’s no way to answer the question I’m guessing you may be asking.  

I am in the middle of renovating my first long term rental and I need new windows for the upstairs unit (it is a top bottom duplex).

But clearly the owner just doesn't care because nothing has been done about it for a very long time, I really don't understand why.

Successfully turned 80% of rent roll from $650 rents to $1150 and drastically improved the NOI.

Quote from @Tiffany Kho: Hi everyone,I manage 2 Airbnb's (one in Orlando and one in San Diego) but now I'm interested in buying a condo in Waikiki located in their resort zone which allows short-term rentals in Oahu.

But here's where to start your research in Dallas County: General Procedures for Filing an Eviction for Non-Payment of RentI also can't answer your second question successfully from my perspective.

Also how long would I need to rent it out for to be considered applicable for an 1031? 

They want to start out wholesaling in their spare time to build capital to buy long term rentals. 

I also am focusing here because its not far from me ;)My question is has anyone had success in this area and if so, what strategy has it been?
