I also network with other investors, and get great contractor leads from them, and sometimes we get together and just chat. 

Is there a network for builders to find suitable R3 land? 

I am talking with my agent and he has a network of other agents which he will shop this around if we do decide to sell.

get as much education as you can about the game, networking is IMPORTANT so dont leave that part out attent local meetups and rei events (the free ones ).

Looking forward to connecting/networking with this community.

Use a wireless router that has a secure network for you and a guest network for tenants and provide it as an included utility.Another option is to place trail cams on the front/back entrances.

I've invested in/renovated a number of single family properties in the suburbs of Philadelphia (Mainline), with values ranging from $400k-$1.3m and decided to tackle a significantly larger project 6 months ago; comps were incredible with high sale prices and very low days-on-market, it looked like a home run.The loan is under an LLC but with a personal guarantee; the renovations are complete and the house is beautiful, but the market has been unbelievably slow compared to the previous 3 years, on which our financials were based. 

In general, the larger the project, the more you'll realize the benefits of modular, especially with custom.

I am assuming they paid what was due but I understand loan mods don’t have to be recorded so there is a chance they worked something out with the bank and they may have a larger loan amount than implied in original deed of trust.  

Find local real estate investor groups and become a familiar face with that community, network with people.
