Everybody has their own strategy that works but it may not work for you. You have to self assess and do what is fitting for your peace of mind. There is more than one way to skin a cat. A lot of things you will learn by trial and error.
Shop around for inspectors and do not just go with the one who offers discounts. Ask if they would have a problem walking through the house with a contractor particularly if the house is new.
Don't trust someone just because they are on the board of a REIA, come with recommendations, and are minister (or say they are). I got ripped off that way by Wendy LoveJoy eventhough she is no longer with REIA. People pay for people to give them recommendations, follow them on twitter and facebook. If they say they are a minister check the church they say they preach at too. I would do more due diligence by checking backgrounds more thoroughly like their criminal, identity and credit.
Always get it in writing. Don't fall for I do not have time to give you a contract now, if you give me the money now I will give you a contract later and I am just trying to save you money so that you do not have to pay more for <fill in the blank> and the contractors can get started now.
If anyone talks to you stupid or sideways run from them. A lot of people fake the funk making you think they have more than they really do. Plus its a form of psychology they use on you to swindle you out of your money. If you feel anything in your gut and you loose sleep stay away from the deal or the person. An example, would be we don't hire inspectors to check rehabs because the city inspector comes anyways and then section 8 also inspects. Hire an inspector engineer that is nonpartial and can give you a proper estimate of repairs.
Don't trust a friend or associate who says their contractor is licensed. Double check by going to the lawyer or the secretary of state website. Also check that they are certified in asbestos, mold, radon etc. Have 3 of these lined up because some will abandon like Abdul Eid, some get ill, some go to jail, some get deported and some get killed. You need backup.
General contractors like to work with their own people. They do not like it when you get your own plumber, electrician, hvac etc.
City inspectors (code enforcers) do make surprise visits. Be careful when using unlicensed and uncertified people. Some places will have your property condemned, that is why it is good to require they get permits before they start working.
A day or two after you submit payment to a contractor that is doing a rehab, call the permit office to make sure they got one and its in their company name.
Don't trust your family to look out for you especially if no formal partnership was established. Besides God and maybe your mama, NO body cares about your money and prosperity more then you do.
When setting up an LLC it is most tax effective if you do so in partnership with a senior citizen. Also find out if you have to register the LLC in the state the properties are in, just in case the LLC is setup in another state.
Have a legal service to turn to. Any legal issues arise always listen to them over someone else. For example, I have this one homeowner, a police officer, on my block who subpeoned me to come to court. When I confronted him, he says it was an accident because he got my name mixed up with someone else. He told me to stay home since I did not agree with him refusing to pay dues. My lawyer said if I do not show that I could be fined and could not believe someone like him advised me on that without offering me the cost of the fine.
Have an accountant and financial advisor that are real estate investors.
Make sure your realtor has a good tenant screening service that checks identity, credit, housing court, criminal background, etc Also check the real estate commission for your state or city and make sure realtors license is current and has not expired or been revoked.
Put a recorder on your phone, turn it on when needed and download to your pc. This is legal in most states so check first. Otherwise download your text messages and communicate more in email.
When selecting a project manager ask what their goal and availability is. You want someone who can commit to checking up on your property. It may even be better if they live in the same locale and not a 40 min drive away. Don't pay all of the money up front either. This goes with all of the people you work with.
Try to keep loud people who appear confident and always putting other people down away from being the president of home owners associations. They just want to boss people around and get into their business, they do not really know what they are doing.
Each state does closings differently. Find out from the state that you will be investing in what is their procedure. Same think for lease options.
Find out what materials are best for the state that you are in. For example in GA luxury vinyl flooring or tile is best in NY anything is good unless the subfloor is concrete then vinyl or laminate is better. In NY tile is only good for bathroom.
