UGH.. this is whats good and bad about our lending these days.. while its cleaned up the Liar loans etc its hampered us 1099 guys..and the more complicated the tax return the harder it is for conventional lenders to get through it.so it really depends on your RMLO and their underwriter if they will look through it and add back in to your bottom line.for a few years there my tax's showed a loss and there was no WAY I could get a loan until I got my TAXABLE income up to a level that worked for them.I then was buying a townhouse in Vegas last year for 300k and I could NOT get a loan on that as my tax returns are about 4 inches thick and no underwriter could really go through it .. so I had to pay cash.. so there I am more than enough cash in the bank to pay for it..
