@Yi ChuThe tried and true, old fashioned, way is to keep a notebook in your car as a mileage log. 

It's the second market we want to build to rent or build spec homes, but a lot of lack of commercial real estate and infrastructure is one of the main reasons it's a secondary market to where I'm based out of columbus ohio  I first went to Lehigh in 1982 on a fact finding mission with the state of California to address these massive subdivisions that were built without proper long range planning and no real infrastructure and would never be approved with modern planning..

If it's a latent defect that's uncovered during a thorough inspection and the buyer wouldn't have been able to determine it before that time, then I think those are reasonable requests - even if they are expensive. 

Reason being is because I'd rather not have my company receive a check, and then turn around and pay it out to me.

It appears the units are below market, however with some cosmetic repairs and perhaps some capex's I feel I could increase the rent by at minimum (based on local comps) 68%.I would offer 85% of list and estimated $20,000 in repairs/upgrades (this is probably a generous estimate - the property appears to be in good shape, basically needs a face lift).With all these figures, including the 50% rule, financing with 20% down @ 3.5%, I come out to a profit of $262 per unit and a cash-on-cash return of 9.53%.So, does this seems reasonable?

The reason why I am asking is because I'm looking at fourplexs in my area and it seems the average price is $ 200,000.

@Jazz Wilson,I'm sure the non-paying tenants are playing a huge part of the seller's reason for selling. 

You can get into the NW Indiana market for very reasonable costs.  

It is not a big deal, however the judge needs to be able to justify the reason you are buying the house below market value.Let me know if you have questions.Bryan
