Do not threaten the tenant but provide her legal written notice, per your states guidelines. 

I won't do this type of contract unless I have dealt with the client a few times.

@Rob Lee I haven't been as active on BP but I have my first deal under contract, a four plex in the Simsbury area.

I under contract to buy a couple of properties out of state. 

I just got something under contract in Birch Run that meets those criteria.

Therefore many attorneys don't understand assignments; simultaneous closings; land contracts; structuring owner financing; or purchasing subject to.  

Ok so I have a property under contract and all the details for the work needed.

Do not cut any corners on a prospective deal to make it look better.Always do the math analysis and try to look at the prospective property before you submit an offer or at least have a clause in the sales contract that allows you some time (about 10 days) to make a detailed inspection without having a penalty that will hurt you too much.  

Additionally, you stated that you read Rich Dad Poor Dad, ask yourself if you think it is the best strategy to buy a primary residence, at market value ("not a killer deal"), live in it for a few years and then hope that you will be able to rent it out for more than your mortgage (and still cover CAPEX, taxes, insurance, property management, vacancy, legal fees, evictions.....etc) Also, keep in mind that you can buy up to a 4 plex with a VA loan (as long as you occupy one of the units for a few years). 

We have a property under contract in Acworth that is on septic and have found out that there may be a stipulation by the county that as homes are sold in this neighborhood they have to be converted.
