Further, the property may qualify for larger loans based on the increased cash flow ability to service debt.  

You do need to have steady employment, decent credit, and not be drowning in debt.

Usually draw fees are very minimal though and if you plan them right, it can be a great way to replenish your cash or pay down debt from rehab.

Eliminate debt, establish a budget, and save.

OR refi one at 70% and get the 45k loan leaving some debt on the line of credit but keeping home 3 free and clear and adding a lot of value to it as well as getting some really good rental income from it.

They also want a priority lien on the property.It sounds like you are looking for someone to fund your down payment, I would be looking for an equity partner over debt as nobody likes to lend money in insecure positions, especially when a borrower lacks skin in the game.How much are you planning to come in with yourself?

The real property investment can be repositioned if it proves disappointing in its original form; it can be refinanced or recapitalized if it has too much or too e pensive debt; inflation over time bales out many bad purchases, and finally the investors knowledge, experience and abilities can be leveraged to turn around a cash flow negative property.I’ll provide an exampleThree years ago we purchased a note from a bank secured by two auto repair facilities with a large amount of excess land.  

You can always leverage rentals within their ability to service the debt. 

Here's the breakdown of rental income and expense analysis:1.Annual Gross Income: $25,800 (Monthly rent of $2,150 x 12)2.Annual Expenses: $25,800 * 0.40 = $10,3203.Annual NOI: $25,800 - $10,320 = $15,4804.Annual Debt Service: $10,680 (Calculated previously using a mortgage calculator with a loan of $131,775, 7.25% interest, and a 30-year term)5.DSCR: $15,480 / $10,680 = 1.45 (approximately)

Not only was my market timing great, but I sold my less promising buildings and used the proceeds to pay down debt on my long term keeper properties, which have higher end tenants and are thus more stable and much easier to manage.
