I assume you always want 3 months (per mortgage) to cover vacancies and about 3 grand per home for repairs.

What is customary in your area, sometimes a note will do it, sometime a hundred bucks, often a grand and in somplaces they may want a % of the sale price offered.

If they were a long term tenant I understand helping them out for a short period (maybe 3-4 months at most) with slight discount to avoid vacancy but you're talking of missing a grand or more per year which is hopefully more than your vacancy rate.

You got 100 grand and your in philly .

also you might want to pay for consultation if this is a major purchase.. if its just a small mom and pop park for a couple hundred grand or less you can take more risk.My dad built and owned a few water companies in CA in the 60s  he could not wait to sell them.. like I said way up in the thread for ME PERSONALLY I would not buy a park without city sewer and water.. but realize that there are tons of them out there with private systems that seem to work fine.. my parks were in Oregon and Washington and were all well over 1 million to 3 million so much more at risk and I don't want to risk the well going bad or DEQ condemning a septic sytem eetc.

If I thought there was a chance for a 4K profit, I might (might) risk 30 grand, and that’s if I had nothing better to do for a couple weeks and had everything lined up perfectly.

You might also consider Islandview (the part that's west of Grand Blvd.) and East Village (which is distinguished from "East English Village" in far east Detroit and "English Village" which is a condo development in Islandview), as there are still deals to be found in both of them.

In slower markets, is that $10 a month rent increase worth a couple grand in turnover costs and all of headache to find another great tenant? 

Recently I have been looking on the west side at Grand Rapids and Kalamazoo.

The cat unit produces $13,000 worth of petrochemical product a minute.That's my first grand slam.Second grand slam happened 6 months later.
