Hey Chris - You may be on to a good deal, but we need more information to see whether there is a creative financing solution you (and the seller) can take advantage of. You said half the property is in an estate - is it correct to understand that this means one brother has passed away? Does this mean the surviving brother will now have $100% ownership?
Assuming now that you're dealing with one brother who is the decision-maker and 100% owner now....how much does he owe on the property? If it's paid off (or nearly), you have seller-finance options. You may be able to offer him full price, or even above, if he is willing to accept a seller-financed transaction. The surviving brother could sell you the property for some down-payment (if he needs it), and you could pay him interest-only payments over a period of years while you cash-flow the property rental, or (better) you could do a principal-only loan (think: installment payments) while you cash-flow it, where your tenants pay down the principal on the mortgage over 10 years, or so. You should probably have a balloon payment at a reasonable point down the road (6-10years?), so the brother doesn't have this money tied up too long...if you have a principal-only loan, you will have paid down the loan significantly after 10 years, and can probably re-finance the balance; you'll have a good amount of equity in the property after 10 years (or whatever you negotiate) of renting it for positive cash-flow.
Lastly, it looks like you're looking to buy for cash, essentially, when perhaps you should consider leverage - you could probably control this property for $5,000-10,000, which would provide some cashflow while building equity and enjoying tax advantages of property ownership).
Thoughts, which I hope spark your creativity....best of good fortune to you.
