However, about eight days later, the seller informed me that they had "changed their mind" and no longer wanted to sell.In the weeks that followed, the seller failed to provide the required documents, including HOA disclosures, the seller’s disclosure, and other essential paperwork, all of which were due within specific timelines per the contract.

Simplicity: TDAs require minimal effort after initial setup, making them attractive for those seeking stress-free investment.For investors like myself, seeking both stability and growth, combining a TDA with real estate investments creates a diversified portfolio.

In rural Idaho, it is much the same way. the counties have minimum requirements and if you keep things on the up and up, it should be fine.Now, in a historical district, that is a different animal all together.

My requirements?

Figure out market rents, deduct expenses to determine NOI, deduct cashflow you want, plug remainder into mortgage calc at current interest rate, then add lender's required down payment.That is how much you offer!

What are the density requirements?

These need 20%-25% down, require a 680-700+ credit score, and 6 to 9 months of reserves (reserves are payments in the bank).
