It's just another cost to factor into your deal and determine what your potential profit is, nothing more.

And for that particular mobile home, you'll have to factor in the cost for appliances and cabinets. 

When getting an appraisal how would that factor into the arv after rehabbing it.

The good news is that, if you find out before you purchase that the work wasn't up-to-code or wasn't recorded, you could opt to use this information as leverage to talk the seller down on price.The other thing I thought of when reading your post was that an appraiser may want to see the new rent values stabilized before factoring them into the appraisal. 

I would recommend that you investigate job growth and population growth as basic determining factors of where to invest.

This is not factoring any vacancies or repairs. 

There is no "moral" factor as long as all parties involved enter into the transaction voluntarily and with congruent, veracious information.

On the other hand, easy access means fewer barriers to entry for new investors and this means seasoned investors like me can no longer rely on the "inconvenience factor" to keep info proprietary and to ourselves.

.- Also noticed no vacancy, unless if the area is really in high demand you may use a lower figure like 2-3% but typically banks will assume 5% vacancy factor when determining net operating income.

This is one of the biggest factors that will determine when I can walk away from my full-time job and pursue real estate full-time.
