One of the biggest red flags I have as a lender (who lends my own money as well as secondary market loan) is when a rookie tells me there goal is to buy 10, 20, whatever properties in the next year. my next question is how many do you own currently?

In addition, if i used fixed rate financing, my biggest expense is fixed.  

Biggest hurdle right now is finding a reasonable cleaner.

Ones of the biggest was that we had to completely replace all the old electric, luckily we were able to save in other areas of our budget to offset most of the costs but not all of them.

My biggest tip here is work with the smaller companies.

For example, if a home has an accurate value and list price of $450,000 and I can get if for $400,000 (because of incentives and timing), and it sells for $490,000 three years later, I am not as concerned with a monthly break even cash flow scenario.- Some builders aren't as friendly to investorsI hope that helps.Thank you so much!

The biggest factor to consider is the new interest rate since it’ll likely be higher than your current 3.2%.

Depending on the lender and program your biggest hurdles might be credit score and income and time in job. 

Ohio is a lengthy foreclosure state and many fees not recoverable0% interest and they don’t pay then you are losing money every month as they have no incentive to payLastly having it at 0% and over priced from its value means if they don’t get a tenant then they just walk away as property is so upside down.If it was me as a seller these are awful terms as a seller.  

Zillow is the biggest real estate website but it helps listing on other sites.
