I started on my own and learned everything by asking more experienced mentors and modeling my practices after them with trial and error.I would also network with other small business owners in your area as they understand business and will help you if you go out of your way to help them.Additionally, I would start writing content or creating videos about real estate in your area so people can see that you are a subject area expert and over time they will decide to work with you.

I would immediately notify the tenant - in writing - that they are responsible for the repair.

The reality is the opposite - if it's not in writing then the PMC doesn't have to provide the service or can charge extra for it!

Can these be tax write offs (home office, phone, car expenses, etc) even though I won't technically be making money for some time until everything is completely built and leased?

I agree with @Christian Styles; consult a landlord attorney in your state.

Fees should be clearly stated in writing, easy to understand, and justifiable.

How should I write the offer?

It's a 4br/2.5ba 1700sqft Usonian style home with a great view (sorry, can't give away the location just yet!). 

All this is part of the planning and should always be in writing, ideally in the LLC OA. 

TAX CERTS are a bizzness not something you do as a passive investor or someone like me who is busy with their core business.. thankfully it was only 30k All that and the SC Hennepin Decision last year now causing states to re-write their laws so that if an investor does somehow end up converting a lien to a deed, that investor may be liable to tax defaulter for the difference between the lien and market value of the property, Tax Liens seem to be VERY MUCH a place where only the big money, interest investors can make it worthwhile.Fortunately, Texas has "immediate" possession Tax Deeds so we keep our focus there.
