The new problem is that I cannot get qualified to refinance a property, let alone buy another because my DTI is too high due to my tax return.What is the most effective way to keep my DTI good while not paying a ton of money into taxes? 

Since I work a very specific niche (mobile homes), there are things I can do to help make things more cost effective. :) 

Looking for owner names, how many years behind, and address.

Think of all the things that could go wrong and see if the lease addresses them: unauthorized pets or tenants, early termination, security deposit, lease violations, late rent, eviction, lawn maintenance, parking, etc.5.

To me, that means a unit is in a good location, renters find the area desirable, and I am able to manage and maintain the product cost-effectively.

Just shoot me a PM with your criteria/email address and I’ll get that set up immediately. 

Call an Escrow company and tell them to “open escrow” on your new purchase. parcel number helps but address is enough.

There are probably hundreds of threads addressing how to screen applications.

Although one plumber I called flat out said it's really not effective- since it cannot tell you where the leak is.

This will eventually have some cooling effect on the housing market.
