Typically you need the combination of the first and second to be 80% loan to value but some HELOCS go to 89.99% Since rates are so low I make a guess that if you added $10000 to your first the payment might remain the same or less.

Vacants, Tired Landlord, Preforclosure, Liens, Bankruptcy, high equity with various combinations. 

A residence with a combination of personal and rental use (when personal use exceeds the greater of 14 days or 10% of rental days and rental use exceeds 14 days).Prorate expense based on personal usec.

Two landlords: one evicted, one sold the place to get away from her, $8K combined debt.

Well, if you sell a STR for $400K and your basis is $200K, you are likely now in the top bracket for that year, when you combine that gain with your personal income.Number one, what does everyone think the practical effect on STR investing will be, if any?
