This is when you decide which side of the line you will be on.  

Feel free to drop a line when ever!

I am doing line item projected expenses and am unsure how to account for these costs.- Other than google searching comparable rentals, is there any way you all accurately project rents as well as vacancies for your areas?

If you want an FHA or conventional owner-occupier loan, you'll need more than $10k to cover the minimal 3.5-5% deposit for your next $350k primary.While in theory, 2x Equity Lines Of Credit could be approved, remember that Lenders only give out a percentage of the homes' values, so, you may not have $74k of borrowable equity!

Even then it might just be better to buy a house down the line unless you are 100% sure you will not move before you can buy the house.Most newbies will do well with rentals even if they aren't the max return kind you see thrown around on BP saving and working towards 3.5% to put down on an FHA house hack should be a fairly achievable goal.

I have subcontractors lined up and know the costs for mostly everything except the foundation. 

Preferably, go for $1 million+ purchase price because you can get better agency financing.There would a lot of work to do finding the deal, performing due diligence, lining up insurance and various inspectors and contractors.

Essentially finding an replacement property and line things up first. 

Plumbing: scope the main lines to make sure there are no obstructions and check for water leaks.
